Which Type Of Rock Is Pegmatite?A. Extrusive IgneousB. SedimentaryC. MetamorphicD. Intrusive Igneous

Answers

Answer 1

Answer:

D. Intrusive igneous

Explanation:

Diorite, granite, pegmatite are examples of intrusive igneous rocks. Extrusive igneous rock: These rocks erupt onto the surface resulting in small crystals as the cooling takes place quickly. The cooling rate is for a few rocks is so quick that they form an amorphous glass. Basalt, tuff, pumice are examples of extrusive igneous rock.

Answer 2

Answer:

It is in fact D. (Intrusive igneous)

Explanation: Intrusive igneous rocks crystallize below Earth's surface, and the slow cooling that occurs there allows large crystals to form. Examples of intrusive igneous rocks are: diabase, diorite, gabbro, granite, pegmatite, and peridotite.

Industrialization is a process that brought negative influences on the earth's natural environment. One of them is climate change.

Industrialization was a process in which the production processes of different products were improved allowing the manufacture of more units with the following characteristics:

Less time wasted.Lower spending of money.Higher performance.

Industrialization influenced most of the countries of the world and caused the great displacement of people from rural areas to cities. This displacement was because the agricultural and manual products produced by artisans and peasants could not compete in the market with the products of large industries.

After several years, humans have shown the negative consequences of this industrialized growth. Well, many of the machines used in these factories work with the combustion of fossil fuels, and the gases produced by them are released into the atmosphere.

On the other hand, the overproduction of products and the effects of marketing has increased the demand for unnecessary products with a very short useful life that increased human waste that pollutes nature.

These environmental damages were intensified by the action of the greenhouse effect because this phenomenon naturally balanced the Earth's temperature, but with the increasing production of gases in factories and other industries, there is a greater concentration of these gases in the atmosphere, which has led to progressive heating of the air and soil.

Ground shaking can transform wet sediments into liquid-like slurries in a process known as ________.

Answers

The process of liquefaction, which is caused by ground shaking, can turn wet sediments into slurries that resemble liquids.

What does ground shaking mean?

The vibrating of the ground caused by an earthquake is referred to as "ground shaking." Body waves and surface waves are responsible for ground trembling. According to a general rule, the severity of ground shaking rises as magnitude rises and falls as distance from the causing fault rises.

Any structures that are in the path of these surface waves may bend or topple over due to the movement. On steeper hills or mountains, the ground shaking may also trigger landslides, mudslides, or avalanches, all of which can harm people and inflict property damage.

The type of building a person is in may transmit the shaking more than another type, which explains why one person close may feel an earthquake while another does not.

Answers

Answer:

c

Explanation:

pls mark me as brainliest pls and tq

Barrier islands have lagoons behind them, they have depositional landforms, and are vulnerable to storm surge. Thus, all of the above.  Therefore, the correct option is D.

Long, narrow islands known as barrier islands run parallel to the continental coast. They are mostly formed by the sand and gravel that are collected by ocean currents and waves.

Estuaries or lagoons are frequently found behind barrier islands. Typically, these lagoons are small bodies of water that are isolated from the ocean by a barrier island. They support many habitats and are distinguished by a combination of freshwater and saltwater.

Thus, the ideal selection is option D.

Answers

A. Stream -> Tributary -> River -> Lake

Stream-Tributary-River-Lake is the path shows how gravity causes water to move. Hence, option A is correct.

How does gravity effect water?

It pushes water downhill and precipitation from the clouds. Air and ocean water are also moved by gravity. In the same way that cool, salty water is denser than warm, less salty water, cool, dry air is denser than warm, humid air. Less dense air and water are forced to flow upward by gravity, which pushes denser air and water downward.

The gravitational pull of the moon causes one bulge on the "near" side of the Earth, which is the side that faces the moon. A second bulge is produced on the other side of the Earth, when inertia is dominant.

In this fashion, two bulges of water are produced by the interaction of gravity and inertia. Only if an object is submerged in water can gravity drag it down through the water.

Thus, option A is correct.
