Marble and Quartzite can be similar in appearance. Name two simple ID techniques that can be used to differentiate between the two?

Answers

Answer 1

Answer:

The scratch test (also known as Mohs Hardness scale) is a way you can test a mineral or stones for its endurance. The minerals you test are scratched by a penny and are measured on a scale of 1-10 on how durable they are. Stones such as quartz have a much stronger endurance to a scratch in the test than marble because of quartzes makeup. Another way to differentiate between the two would be to look at the mineral’s luster. The luster of a mineral is the way the light bounces off of its surface. There are different lusters that different minerals give off. There are two major types of lusters and they are Metallic or nonmetallic. A metallic luster is typically shiny while a nonmetallic luster can have many different types like musty or solid. Because quartz is a quartz it will be metallic because it is shiny while marble will be nonmetallic because it does not reflect light.

I hope this helps! :D

Why do political discussions of the twentieth century tend to fixate on Fascism or Communism
and not on colonialism?

Answers

Answer:

Because most of the world was already colonized, so most of the political discussions were based on keeping control at home.

Fascism does not require a government-controlled command economy, whereas communism does. Because there is no private ownership of property or growth of money, both fascism and communism are classless societies. The state owns all means of production.

How was fascism or communism received during the 20th century?

Fascism is a nationalistic, top-down system with rigid class roles that is governed by an all-powerful dictator, in contrast to communism, which is based on the idea of economic equality and advocates for a classless society.

The early to mid-20th century saw the rise of fascism and communism, both of which had their inception in Europe. A political ideology that is autocratic is fascism.

On the other hand, socialism is a political philosophy in which members of a society own the production equipment. Over a nation, a fascist leader possesses absolute control and authority.

Socialist leaders, on the other hand, divide up authority and power among the states.

Would you expect sediments found in the Cedar Creek alluvial fan to be texturally and compositionally mature, or texturally and compositionally immature

Answers

Answer:

I would expect the sediments found in the Cedar Creek alluvial fan to be textually and compositionally immature.

Explanation:

I would expect the sediments found in the Cedar Creek alluvial fan to be textually and compositionally immature because this type of sediment is more common than usual to be present in most alluvial fans. This is probably due to the lack of weathering in these regions, which ends up leaving the sediments little worked, since their structures and compositions are not influenced by weathering factors, with great impact.

Briefly explain why there was a split in Islam that resulted in the creation of the two different sects.

Answers

Answer: It is not realy a "split". That would imply two relatively large groups. The fact is that at least 85% of those who call themselves Muslim are all from one group. They are the people who follow the Qur'an and the example of Prophet Muhammad (peace be upon him). They are called 'sunni' Muslims, by some people. In fact, they are simply true Muslims.

The other 15% are all deviant sects that have corrupted the true, original teachings. Anyone who studies Islam can see how the other groups have changed the original message.

Shiites, Ahmadiyyah, Alawi, Ismaili, Druze are some names of deviant groups.

In fact, Muhammad said that there would be such deviants; and he condemned their teachings as leading away from God. He said that the only rightly-guided group would be the one that stuck to the Qur'an and to his example. We thank God that it is the clear majority.

For an understanding of why the Shiite sect developed, you can go to Wikipedia for a detailed explanation. For examples of how they have gone astray from the healthy and true religion, you can go to You Tube and search: Real Shiah Faces.

How would you be able to immediately tell whether a shale parent rock had been subjected to either intermediate-grade contact metamorphism or intermediate-grade mountain belt (regional) metamorphism?

Answers

Answer:

On the basis of heat and pressure the rock undergoes transformation.

Explanation:

The contact metamorphism occurs when magma comes into contact with the already existing body of rocks. Regional metamorphism occurs in wider areas of earths crust. It occurs in areas where the rocks have undergone deformation at time of orogenetic events. Metamorphic grades refers to the changes in the processing of rocks form low to high grade.  The shale rocks are metamorphized under intense heat and pressure to form slate thereby increase in the grade quality. If the rocks are subjected to contact metamorphism then slate is formed and if its regional metamorphism then phyllite, then schist, and finally, gneiss are formed.

Which of the following scenarios are examples of positive-feedback mechanism? Check all that are correct

Answers

Answer: Deforestation near the Sahara Desert causes the soil to be exposed. Exposed soil evaporates moisture more readily. Insufficient moisture leads to the death of trees.

A warmer atmosphere causes more evaporation. Water vapor is a greenhouse gas, so this increases the temperature.

Warmer temperatures cause snow to melt. This makes the ground darker, allowing more solar radiation to be absorbed. The warmer ground warms the atmosphere.

Explanation:

Positive feedback mechanism refers to, the changes in a system, which induces further changes. It exists in an environment that leads to the rise in the causative effect of the environment which can change the precipitation, temperature, precipitation and other climatic conditions of the area

Therefore, the examples of positive-feedback mechanism include:

• Deforestation near the Sahara Desert causes the soil to be exposed. Exposed soil evaporates moisture more readily. Insufficient moisture leads to the death of trees.

• A warmer atmosphere causes more evaporation. Water vapor is a greenhouse gas, so this increases the temperature.

• Warmer temperatures cause snow to melt. This makes the ground darker, allowing more solar radiation to be absorbed. The warmer ground warms the atmosphere.

Why the mode of pollination in maize is cross-pollination? Why it is important to cover the ear shoot with a butter paper bag before the emergence of silks? What could be the consequences if a few silks emerge before bagging?

Answers

Answer:

The correct answer is -

1. due to the fact that maize is a monoecious crop that has male and female flowers in separate parts of the same plant that distributed pollen by the wind to other female parts of another maize plant.

2. Once silks are visible, they may already  be contaminated with foreign pollen, so it is vital that ears shots are  bagged before the emergence of silks.

3. If silks have emerged before bagging which means they are already been contaminated with other pollen and which will affect the process of hand pollination and have other varieties than desired.
