what igneous rock has no visible crystals as a result of rapid cooling?

Answers

Answer 1

The type of igneous rock that has no visible crystals as a result of rapid cooling is known as volcanic glass or obsidian. The rock is solidified from a molten state very quickly, hence the lack of crystals or mineral growth. Obsidian can range from black, dark brown to red-brown in color.

Obsidian is a glass-like rock that is formed from rapidly cooled lava. The rock is usually black in color, although it can also be brown, green, or red. The rock is hard, dense, and brittle, and is often used in the manufacture of tools, weapons, and jewelry.Obsidian is usually found in areas of volcanic activity.

The rock is formed when lava cools so quickly that there is not enough time for crystals to form. Instead, the rock solidifies into a glass-like substance. The lack of crystals makes obsidian very smooth and shiny.Obsidian is an important rock for archaeologists and anthropologists. T

he rock has been used for thousands of years to make tools and weapons. Obsidian is extremely sharp, and can be used to make knives, arrowheads, and other cutting tools.

Give logics I favor of your answer.

Answers

Irony aspects of democracy Democracy has its share of irony aspects such as corruption, lobbying, apathy, and voter suppression. Although it is supposed to represent the people's voice and choices, it may result in unequal representation.

A small percentage of the population controls the wealth and political power, and they will always attempt to sway the government policies and decisions to their advantage. Moreover, voters may become apathetic, resulting in a low voter turnout or even fraudulent activities in the elections. Lastly, voter suppression, which involves restricting certain groups' voting rights, contradicts democracy's principles.Governance and democracyDemocracy is a system that allows citizens to express their views and elect their representatives, who govern the country. Good governance, on the other hand, is a comprehensive concept that encompasses every aspect of government operations, including service delivery, accountability, transparency, rule of law, and citizen participation. While democracy and good governance are closely related, democracy does not always guarantee good governance. A country can have free and fair elections but lack efficient institutions, leading to poor public service delivery, corruption, and weak rule of law.Do you think democracy is the only remedy for good governance and development?Democracy is not the only remedy for good governance and development. Other factors such as a stable political system, economic growth, strong institutions, and effective leadership also play a crucial role.

3) Why do hurricanes lose their intensity once they hit landfall?

Answers

Hurricanes lose their intensity once they hit landfall due to the reduction in the energy source that they require. When the hurricane is over water, it is continuously supplied with warm and moist air which provides energy to maintain and enhance its strength.

However, once the hurricane hits land, it loses its energy source because the surface of the land is drier and cooler than the water and does not provide the hurricane with the heat and moisture that it needs to maintain its intensity. Consequently, the hurricane gradually loses its strength, as the supply of warm moist air diminishes and it starts to interact with land-based obstacles.

In addition, the topography of the land can also play a crucial role in the weakening of hurricanes. Mountains, for instance, can cause hurricanes to break up or cause them to deflect around them. Therefore, the majority of hurricanes lose their intensity once they hit landfall and can dissipate into a series of smaller storms.

3. A brief answer to the mechanism of Cataclastic metamorphism

Answers

Cataclastic metamorphism refers to a type of metamorphism that takes place due to the fracturing and crushing of rocks.

Cataclastic metamorphism occurs at the uppermost level of the earth's crust and is common in areas that have experienced intense deformation due to tectonic activities. The term cataclastic metamorphism was first used by Sander in 1926. Cataclastic metamorphism occurs when rocks are subjected to differential stress, which causes them to break down into smaller particles.

The particles then undergo deformation and recrystallization to form new minerals, which are often different from the original minerals. Cataclastic metamorphism is characterized by the presence of numerous faults and fractures in the rocks. These fractures serve as pathways for the movement of fluids, which can cause changes in the chemical composition of the rocks. The fluids can also lead to the deposition of new minerals, which can further alter the structure and texture of the rocks.

Cataclastic metamorphism is also associated with high temperatures and pressures, which can cause rocks to melt and recrystallize. The process of melting and recrystallization is known as dynamic metamorphism and can lead to the formation of new rocks, such as gneiss and schist.

If the marginal cost of preservation is $500 per mile, how many miles would be preserved in an efficient allocation?
How large is the economic surplus?
Suppose the market demand function (expressed in dollars) for a normal product is P = 80-1.0Q, and the marginal cost (in dollars) of producing it is MC=1Q, where
P is the price of the product and Q is the quantity demanded and/or supplied.

How much would be supplied by a competitive market?
Compute the consumer surplus, producer surplus and economic surplus.

Answers

The consumer surplus, producer surplus, and economic surplus are $800, $800, and $1600, respectively. The given inverse demand function for the 100 people in the community is P = 10 – 1.0Q where P is the per-mile price and Q is the number of miles preserved. Given marginal cost of preservation is $500 per mile.

The efficient allocation of miles preserved would occur when the marginal cost is equal to the marginal benefit, which is the inverse demand function.Substituting $500 for the marginal cost in the inverse demand function we get;P = 10 - 1.0QP + 1.0Q = 10Q = 5 milesTherefore, 5 miles would be preserved in an efficient allocation. Economic surplus is the sum of consumer surplus and producer surplus.The consumer surplus is the difference between what consumers are willing to pay for a good or service and the actual price they pay. The producer surplus is the difference between the actual price producers receive for a good or service and the minimum price they would be willing to accept for the good or service.Suppose the market demand function (expressed in dollars) for a normal product is P = 80-1.0Q, and the marginal cost (in dollars) of producing it is MC=1Q.The quantity supplied in a competitive market is equal to the quantity demanded.Thus, equating demand and supply equations:80 - 1.0Q = 1Q => 80 = 2Q => Q = 40Thus, 40 units of the product would be supplied by a competitive market.Consumer Surplus = 1/2 x 40 x (80 - 40) = $800Producer Surplus = 1/2 x 40 x (40) = $800Economic Surplus = $800 + $800 = $1600Therefore, the consumer surplus, producer surplus, and economic surplus are $800, $800, and $1600, respectively.

Is it possible to have an infinite blueshift (z = 1)? If so,
what would that correspond to? Consider peculiar velocities as well
as recession velocities in your answer, and explain your
reasoning.

Answers

In the context of cosmology and the redshift of light, it is not possible to have an infinite blueshift. The redshift of light is caused by the expansion of the universe, and it is a result of the stretching of the wavelength of light as space itself expands. The redshift is described by the parameter z, which represents the observed change in the wavelength of light compared to its emitted wavelength.

As the universe expands, the wavelength of light from distant objects gets stretched, resulting in a redshift. This redshift can take on values from zero (no shift) to positive values, indicating a longer wavelength and hence a greater redshift. However, it cannot exceed infinite redshift or correspond to an infinite blueshift.

The reason for this limitation is related to the fundamental principles of relativity and the finite speed of light. According to special relativity, the speed of light in a vacuum is constant and serves as an upper limit for the velocity of any object in the universe. Since nothing can travel faster than the speed of light, the maximum amount by which light can be redshifted is limited.

In the context of peculiar velocities, which represent the velocities of objects relative to the overall expansion of the universe, they can introduce additional components to the observed redshift. Peculiar velocities arise from the motions of galaxies or other celestial objects within local structures, such as galaxy clusters or superclusters. These motions can cause deviations from the overall expansion of the universe and introduce additional shifts in the observed wavelength of light.

However, even with the inclusion of peculiar velocities, the total redshift observed can only be finite and cannot result in an infinite blueshift. The finite speed of light and the limited expansion of the universe impose constraints on the observed redshift values, preventing them from reaching infinity.

Therefore, while redshifts can take on various positive values, corresponding to different degrees of stretching and increasing wavelength, an infinite blueshift is not possible in the context of cosmology.

Which of the following is a correct formula for your latitude as determined by observing a star of declination "dec" at an altitude "alt" above your Southern horizon?
dec + alt = latitude
dec - alt = latitude
90 - dec + alt = latitude
90 + dec - alt = latitude

Answers

The correct formula for determining latitude based on observing a star of declination 'dec' at an altitude 'alt' above the southern horizon is option 90 + dec – alt = latitude. Thus the correct answer is option D.

Latitude is the angular distance between a point on the Earth's surface and the equator, measured in degrees. To determine latitude, we must consider the star's declination, the angular distance north or south from the celestial equator.

In the formula 90 + Dec - Alt = Latitude, the term "90" represents the position of the celestial north pole, which is directly above the north pole and corresponds to 90 degrees latitude. By subtracting the star's declination "dec" (which can be positive or negative depending on whether it is north or south of the celestial equator) and then subtracting the altitude "alt" (measured from the southern horizon), we get to find the angles between the stars.

Which is the best technique to find the age of the Earth? A. paleomagnetism B. Radiocarbon (C14) method C. Dendrochronology D. Potassium/Argon (K40/Ar40) method QUESTION 85 Which geologic time unit means evident life? A. Cryptozoic B. Phanerozoic C. Paleozoic D. Cenozoic

Answers

A. The best technique to find the age of the Earth is D. Potassium/Argon (K40/Ar40) method.

The Potassium/Argon (K40/Ar40) method is considered the best technique to determine the age of the Earth. This method relies on the radioactive decay of potassium-40 isotopes into argon-40 over time. By measuring the ratio of potassium-40 to argon-40 in rocks and minerals, scientists can calculate the age of the samples. This method has been extensively used in dating volcanic rocks and has provided valuable insights into the age of the Earth, with estimates currently around 4.5 billion years. The K40/Ar40 method is highly reliable and widely accepted in the scientific community for determining the age of the Earth.

B. The geologic time unit that means evident life is B. Phanerozoic. The Phanerozoic Eon, which began around 541 million years ago and continues to the present day, is characterized by the abundant and evident presence of life. It is divided into three eras: Paleozoic, Mesozoic, and Cenozoic. The Phanerozoic Eon is known for the proliferation and diversification of complex multicellular organisms, including plants, animals, and marine life. The term "Phanerozoic" itself derives from the Greek words for "visible life," emphasizing the prominent existence and diversity of life forms during this eon.

What are some of the market-based instruments suggested to address the environmental challenges? List 4 Market-based instruments. Why do Muradian and Gómez-Baggethun call Market-based instruments a flawed category? Justify your answer using two Market-based instruments

Answers

Market-based instruments are economic approaches that involve establishing a price for environmental services and goods, such as pollution permits or taxes. These policies encourage pollution control in a cost-effective way, promoting the development of market-driven solutions to environmental problems. However, it is an imperfect instrument, according to Muradian and Gómez-Baggethun, because it depends on a series of assumptions that might not hold in the real world.

Market-based instruments are considered as the most promising instruments for conserving the environment. These are powerful tools that can help solve a variety of environmental issues, such as climate change, biodiversity conservation, deforestation, etc. The first instrument is Polluter Pays Principle. It requires that any pollution caused by a business, industry, or individual be held accountable for it. This involves making the polluters pay for the damages they have caused. The second instrument is the Cap and Trade system, which places a limit on the amount of pollution that can be produced and creates a market for pollution permits.

Despite their popularity, market-based instruments have been criticized for their limitations and flaws by scholars such as Muradian and Gómez-Baggethun. They claim that the market-based approach's theoretical assumptions do not align with the way markets actually work. As a result, some environmental problems have not been adequately addressed, and there have been many negative impacts on social and ecological systems. Therefore, it is essential to acknowledge that the market-based approach has limitations, and other methods should be considered for addressing environmental challenges.

16. A rectangular suppressed weir 1 m high extends across a rec- tangular channel 6 m wide in which the flow is 2.80 m³/s. Determine the depth of water upstream from the weir.

Answers

Hydrology is the scientific study of water in the Earth’s atmosphere, on the land, and in the soil and rocks. It involves understanding the water cycle, water quality, and the physical, chemical, and biological processes that affect water.

A rectangular suppressed weir 1 m high extends across a rectangular channel 6 m wide in which the flow is 2.80 m³/s. Determine the depth of water upstream from the weir.In a suppressed rectangular weir, the downstream edge of the crest is above the level of the approach channel bed.

Thus, the weir is partially submerged. The depth of water upstream of the weir is less than the height of the weir because of this.The flow over the weir can be calculated using the Francis formula as follows:

Q = Cd x L x (H + (2/3)h)^1.5

where,Q = Flow over the weir,

L = Length of the weir,H = Height of the weir,

h = Head of water above the crest of the weirCd = Coefficient of dischargeThe head upstream of the weir is calculated as follows:

h = Q/CdL(H + (2/3)h)^0.5We are given,

L = 6 mH = 1 mQ = 2.80 m³/sWe will assume the value of Cd to be 0.60.Substituting the values of L, H, Q, and Cd in the above equation,

we get,2.80 = (0.60)(6)(1 + (2/3)h)^1.5Solving for h, we get,h = 1.39 mThe depth of water upstream from the weir is 1.39 m.

Answer: The depth of water upstream from the weir is 1.39 m.

History Question.
Define and explain what is the FIRST Industrial Revolution. What is
its impact on the Modern World? How did it especially affect the
Europe and America? Lastly, thoroughly discuss i

Answers

The FIRST Industrial Revolution marked a significant shift in manufacturing and production processes, fueled by mechanization and steam power. It began in the late 18th century in Britain and had a profound impact on the Modern World, transforming societies and economies worldwide. Europe and America were particularly affected by this revolution, as they experienced rapid industrialization and urbanization.

During the First Industrial Revolution, advancements in technology such as the steam engine, textile machinery, and iron production techniques transformed various industries. The introduction of mechanized production methods led to increased efficiency and output, enabling the mass production of goods. This shift had far-reaching consequences. It accelerated urbanization as people migrated from rural areas to cities in search of employment opportunities in factories. The emergence of factory systems, along with the growth of trade and transportation networks, fueled economic expansion and the rise of capitalism.

In Europe, the First Industrial Revolution had a profound impact on society. It brought about significant changes in the structure of the workforce, as people transitioned from agricultural work to factory labor. This shift led to the rise of the working class, with its own distinct social and economic challenges. The industrialization process also sparked social and political movements, such as the formation of trade unions and calls for workers' rights and improved working conditions.

Similarly, in America, the First Industrial Revolution transformed the country's economic landscape. It fueled the growth of industries such as textiles, iron and steel, and manufacturing. The expansion of the railroad system facilitated the transportation of goods and facilitated westward expansion. Industrialization also played a pivotal role in the development of capitalism and the accumulation of wealth by entrepreneurs and industrialists. However, it also led to the rise of social inequality and income disparities.

We need clean water supply for daily usage such as drinking, cooking, cleaning and so on. In Malaysia, majority of the water supply comes from the rivers. Briefly explain the process at the wastewater treatment plant before discharging the treated water into the river or stream.

Answers

The process at the wastewater treatment plant before discharging the treated water into the river or stream in Malaysia is multi-staged and it involves various methods of treating and purifying the wastewater. In the first stage, the wastewater is collected into the wastewater treatment plant and screened for solids, organic matter and other debris.

This ensures that large objects and non-water material are removed from the wastewater. The wastewater is then separated from the solid wastes and passed through grit removal tanks, which remove grit and sand particles. Next, the wastewater is transferred into the primary sedimentation tanks where the wastewater is allowed to settle, and the organic matter is separated. This process is known as primary treatment and it removes a large percentage of the suspended solids and organic matter in the wastewater. In the secondary treatment process, the wastewater undergoes biological treatment. The wastewater is aerated, and bacteria and other microorganisms are added to it. These microorganisms digest the organic matter in the wastewater and convert it into biomass and carbon dioxide. The remaining microorganisms are then settled out of the wastewater in the secondary sedimentation tanks. Finally, the treated wastewater is disinfected with chlorine or other disinfectants before being discharged into the river or stream. This is to kill any remaining pathogenic bacteria and viruses in the wastewater. The treated wastewater is tested to ensure that it meets the discharge standards set by the Malaysian Department of Environment (DOE) before being released into the river or stream. The treated wastewater is safe for the environment, aquatic life, and humans, and it can be reused for non-potable purposes.

Prevailing air currents that are ascending (moving from lower to higher elevation) O become cooler and create wetter conditions than descending air currents O occur along 0° latitude band c above a and c above O become warmer and create drier conditions than descending air

Answers

Prevailing air currents in the equatorial region move upwards and create wet conditions, while air currents in the subtropics move downwards, leading to warm and dry conditions.

Prevailing air currents that are ascending moving from lower to higher elevation become cooler and create wetter conditions than descending air currents. However, air currents that are descending moving from higher to lower elevation become warmer and create drier conditions than ascending air currents.These opposing air currents occur in the equatorial region, and they have several characteristics. At the equator, a low-pressure zone exists, and the air is rising from the surface as a result of this low pressure. The rising air is cooled, leading to the development of clouds and precipitation.The reason why the air is rising in the equator region is that the sun shines directly overhead throughout the year, resulting in high temperatures. This heating effect causes the air to rise, leading to the formation of a low-pressure zone. The temperature is so high that it causes the air to rise and, as a result, produces a lot of precipitation in the area.Therefore, the equator region has the highest precipitation rates globally. Conversely, as the air descends in the subtropics, the air gets compressed, resulting in warmer and drier conditions.

On a summers' night, on the shores of a local Vancouver beach, visitors walking tide line would experience 'this'.

a) A sea breeze

b) An on shore wind

A land breeze

d) None of the above

Answers

On a summer night, on the shores of a local Vancouver beach, visitors walking the tide line would experience "a sea breeze".A sea breeze refers to a wind that blows from the sea towards the land due to the temperature differences between the land and sea.

During the day, the sun heats the land quicker than the sea, causing the warm air over the land to rise. This is replaced by cool air coming from the sea, creating a sea breeze. At night, the situation is reversed, and the land cools down quicker than the sea, and the cycle is reversed. Therefore, visitors walking on the tide line of a Vancouver beach during summer would experience a sea breeze.  Please note that as per Brainly's guidelines,  so let me add a little more.The sea breeze is a refreshing wind, and one that is often felt in many coastal regions.
