What type of metamorphic grade is responsible for the conversion of granite into granitic gneiss?
- Low Grade
- Very Low Grade
- High Grade
- Medium Grade
Please explain!
High grade
Explanation:
Granite is converted into granitic gnesis in high grade of metamorphic phase The high grade refers to the temperature above 50°C or 323K around.Because increasing temperature decreases water crystals in graniteAnswer:
High Grade
Explanation:
The metamorphic grade responsible for the conversion of granite into granitic gneiss is generally high grade metamorphism.
Gneiss is a foliated metamorphic rock that is typically formed from the metamorphism of pre-existing rocks such as granite. During high grade metamorphism, the temperature and pressure conditions are high enough to cause recrystallization of the minerals in the parent rock, resulting in the formation of new minerals and the development of a foliated texture.
In the case of granite, high grade metamorphism can cause the feldspar and quartz grains to recrystallize and form elongated grains that are aligned parallel to the direction of greatest stress. This results in the development of a foliated texture that is characteristic of gneiss.
While low and medium grade metamorphism can also cause changes in the mineralogy and texture of rocks, they are generally not sufficient to produce the distinctive foliated texture of gneiss. Very low grade metamorphism typically results in the formation of non-foliated rocks such as quartzite or marble.

Chemical weathering is prominent in environments characterized by:
- Higher rainfall and temperatures.
- Lower rainfall and temperatures.
- Lower rainfall, but higher temperatures.
- Higher rainfall, but lower temperatures.
Answer:
Higher rainfall and temperatures.
Explanation:
Chemical weathering is a process that breaks down rocks and minerals through chemical reactions with water and other substances in the environment. The rate and intensity of chemical weathering is influenced by a variety of factors, including temperature, rainfall, and the chemical composition of the rocks and minerals being weathered.
Of the options you provided, the environment that is most likely to be characterized by prominent chemical weathering is "Higher rainfall and temperatures." This is because chemical weathering is generally more rapid and intense in warm, humid environments where there is abundant water to facilitate chemical reactions.
In these environments, water can dissolve minerals in the rocks and carry them away, or react with the minerals to form new compounds that are more easily weathered. The combination of high temperatures and abundant rainfall also provides favorable conditions for the growth of vegetation, which can further enhance chemical weathering by producing organic acids that can dissolve minerals in the rocks.
While lower temperatures and lower rainfall can also contribute to chemical weathering, the process is generally slower and less intense in these environments.

Which of the following is not a true statement about mineral properties?
- Calcite dissolves rapidly releasing visible bubbles of carbon dioxide gas so the acid test is useful for identifying if the mineral calcite is present.
- Luster is the way in which a mineral reflects light.
- Some minerals have a natural magnetism such as a magnetite which is why geologists test minerals with magnets to check for this characteristic.
- Pyrite has a metallic luster and is a yellowish mineral but it will not streak the same color as gold.
- Fluorescent minerals emite visible light when they are exposed to radiation.
Please explain!
The sentence that is not a true statement about mineral properties is option A. Calcite dissolves rapidly releasing visible bubbles of carbon dioxide gas so the acid test is useful for identifying if the mineral calcite is present. Hence, the correct answer is option A. Read below why option A. is the sentence that is not true of the minerals.
Why is option A not true?The bubbling release of carbon dioxide gas is so weak that one needs a hand lens to observe single bubbles slowly growing in the drop of hydrochloric acid - or so vigorous that a flash of effervescence is produced. This is the case as against the proposition stated in the option that it is visible whereas, it is not visible without a hand lens.
Therefore the correct answer is as given above.

Answer:
The statement "Pyrite has a metallic luster and is a yellowish mineral but it will not streak the same color as gold" is not a true statement about mineral properties.
In reality, pyrite, also known as fool's gold, does have a metallic luster and is often a brassy yellow color. However, when pyrite is streaked on a streak plate or any other rough surface, it leaves a greenish-black or dark gray streak, which distinguishes it from gold. Gold, on the other hand, leaves a golden-yellow streak.
Explanation:
The other statements you mentioned are true:
Calcite does dissolve rapidly in acid, releasing visible bubbles of carbon dioxide gas, which makes the acid test useful for identifying its presence.Luster refers to the way in which a mineral reflects light, and it is one of the important properties used in mineral identification.Some minerals, such as magnetite, exhibit natural magnetism, and geologists can use magnets to test for this characteristic.Fluorescent minerals do emit visible light when exposed to certain types of radiation, which is why they are used in fluorescent mineral displays.Remember that understanding the properties of minerals is crucial for their identification and classification in the field of geology.
Understanding the properties of minerals is an essential aspect of mineralogy and geology. Here are some additional details about mineral properties:
Hardness: Hardness is a measure of a mineral's resistance to scratching or abrasion. It is often assessed using the Mohs scale of hardness, which ranks minerals from 1 (softest) to 10 (hardest). For example, talc has a hardness of 1, while diamond has a hardness of 10.Cl34vage and Fracture: Cl34vage refers to the way a mineral breaks along planes of weakness, producing smooth, flat surfaces. Fracture describes the manner in which a mineral breaks when no cl34vage planes are present, resulting in irregular or rough surfaces.Color: Color can be a useful property for identifying minerals, but it can also be misleading. Many minerals exhibit a range of colors, while others may be colorless. Additionally, impurities within a mineral can cause variations in color.Streak: Streak refers to the color of a mineral's powder when it is scraped across a rough surface. It is often determined by rubbing the mineral on a streak plate, which is an unglazed porcelain tile. Streak color can differ from the mineral's external color and can aid in identification.Density: Density is the measure of a mineral's mass per unit volume. It helps distinguish between minerals with similar appearances but different compositions. Density is typically reported in grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).Crystal Habit: Crystal habit refers to the characteristic shape and arrangement of crystals in a mineral. Different minerals exhibit distinct crystal habits, such as cubic, prismatic, tabular, or fibrous.Specific Gravity: Specific gravity is the ratio of a mineral's density to the density of water. It provides a measure of a mineral's heaviness compared to water and can aid in identification.These properties, among others, contribute to the identification and classification of minerals. It's important to note that some properties, such as luster and streak, are observable with the bare eye, while others, like hardness and specific gravity, may require specialized tools for accurate measurement.

Discuss in detail the impact of European farm animals on the ecosystems of Oceania. Why have the Dingo fence and the Rabbit Proof fence been necessary in Australia.? What does this tell us about the vulnerability of Oceania’s environment to invasive species, and toe changing patterns of food consumption based on introduced domesticated animals? Finally, why are coral reefs such as the Great Barrier Reef ecologically important to the coastal zones of Australia, and how are they threatened by climate change
The evolution of flora and fauna across the islands of Australia and Oceania is very unique.
Many species of plants and animals reached the southern Asian islands during the last ice age, when sea levels were low enough for travel. THE DINGO Fence was built to keep dingos out of sheep pastures in South East Australia. As Australia's largest terrestrial predator, dingoes pose a major threat to livestock.
The Rabbit Proof Fence was built to protect Western Australia's crops and grasslands from rabbit disease. Introduced to Australia in Victoria in the 1850s, the pest quickly spread throughout eastern Australia.
They are home to a quarter of the ocean's marine life, generate clean air and protect vulnerable coastlines from erosion, flooding and storms. In Australia, our Great Barrier Reef is an irreplaceable and vital part of our ecosystem - and our economy.

Answer: it is easy
Explanation:
defenition: A landslide is defined as the movement of a mass of rock, debris, or earth down a slope. Landslides are a type of "mass wasting," which denotes any down-slope movement of soil and rock under the direct influence of gravity.
causes: Landslides are caused by disturbances in the natural stability of a slope. They can accompany heavy rains or follow droughts, earthquakes, or volcanic eruptions. Mudslides develop when water rapidly accumulates in the ground and results in a surge of water-saturated rock, earth, and debris.
effects: The negative effects of landslides are: they damage/destroy ecosystems, harm agriculture, damage built infrastructure, lead to economic losses, deaths, social disruption and can lead to other hazards.
precautions: To keep landslides from hitting your home and property, consider adding nets, retaining walls, and planting sturdy vegetation, especially on slopes or in places where wildfire has destroyed plants and trees. Do not remove vegetation that may help prevent erosion. Add sandbags in exposed areas.
