New crust is being produced at a mid-ocean ridge. How does the affect the total size of the crust?
(A)The total amount of crust is always increasing because it is always created.
(B)The new crust is denser than older crust, so it sinks.
(C)The total amount of crust is always decreasing because of earthquakes.
(D)The crust size remains constant because older crust is melted at subduction zones..

Answers

Answer 1

Answer:

The crust size remains constant because the older crust is melted at subduction zones.

Explanation:

The crust is constnatly created on Earth, but the crust is constantly getting destroyed as well. This situation leads to the total size of the crust being roughly at the same level, or rather constant, as one side a new one emerges, while at the same time, on the other side it gets destroyed.

The vast majority of the new crust is formed where there are divergent plate boundaries. Here, a gap opens up between the plates that move away and magma is constantly rising to the surface and creates new crust. When it comes to the destruction of crust, it occurs at subduction zones. Here, one plate moves below another plate, and as it does it reaches the upper mantle where it gets melted and recycled because of the high temperatures and pressure.

Why does a small percentage of the country's population live in China's West?

Answers

While China's population has held steady through that time, the economic growth has driven people from the country's interior farmland to the coast, and the combination of industrialization and a swelling coastal population is taking its toll on the marine environment, according to the researchers.

Due to unfavorable climate and soil for farming and production, Western China is not conducive to living. Due to this, China's western regions are sparsely populated compared to other parts of China, where production and farming are more conducive.

The eastern, coastal provinces are much more densely populated than the western interior because of the historical access to water.

high​

Answers

Answer:

Atmospheric temperature is the graduation of heat that takes place in a specific place on the planet. The higher the heat, the higher the temperature, and conversely, the lower the heat, the lower the temperature.

High temperatures influence the climate by lowering the ectopascal pressure and increasing the humidity of the environment, since it evaporates the water that is on the surface, generating clouds and eventual rains. The opposite occurs with cold temperatures: ectopascal pressure rises, and humidity decreases.

What is most likely at the location of the volcanoes and ocean trenches?

Answers

Answer:

Generally they lie seaward of and parallel to adjacent island arcs or mountain ranges of the continental margins. They are closely associated with and found in subduction zones. Hope this helps! =)

Answer:

Ocean trenches are long, narrow depressions on the seafloor. These chasms are the deepest parts of the ocean—and some of the deepest natural spots on Earth. Ocean trenches are found in every ocean basin on the planet, although the deepest ocean trenches ring the Pacific as part of the so-called “Ring of Fire” that also includes active volcanoes and earthquake zones.

 

Ocean trenches are a result of tectonic activity, which describes the movement of the Earth’s lithosphere. In particular, ocean trenches are a feature of convergent plate boundaries, where two or more tectonic plates meet. At many convergent plate boundaries, dense lithosphere melts or slides beneath less-dense lithosphere in a process called subduction, creating a trench.

 

Ocean trenches occupy the deepest layer of the ocean, the hadalpelagic zone. The intense pressure, lack of sunlight, and frigid temperatures of the hadalpelagic zone make ocean trenches some of the most unique habitats on Earth.

Subduction Zones

When the leading edge of a dense tectonic plate meets the leading edge of a less-dense plate, the denser plate bends downward. This place where the denser plate subducts is called a subduction zone.  

 

Oceanic subduction zones almost always feature a small hill preceding the ocean trench itself. This hill, called the outer trench swell, marks the region where the subducting plate begins to buckle and fall beneath the more buoyant plate.

 

Some ocean trenches are formed by subduction between a plate carrying continental crust and a plate carrying oceanic crust. Continental crust is always much more buoyant than oceanic crust, and oceanic crust will always subduct.  

 

Ocean trenches formed by this continental-oceanic boundary are asymmetrical. On a trench’s outer slope (the oceanic side), the slope is gentle as the plate gradually bends into the trench. On the inner slope (continental side), the trench walls are much more steep. The types of rocks found in these ocean trenches are also asymmetrical. The oceanic side is dominated by thick sedimentary rocks, while the continental side generally has a more igneous and metamorphic composition.

 

Some of the most familiar ocean trenches are the result of this type of convergent plate boundary. The Peru-Chile Trench off the west coast of South America is formed by the oceanic crust of the Nazca plate subducting beneath the continental crust of the South American plate. The Ryukyu Trench, stretching out from southern Japan, is formed as the oceanic crust of the Philippine plate subducts beneath the continental crust of the Eurasian plate.

 

More rarely, ocean trenches can be formed when two plates carrying oceanic crust meet. The Mariana Trench, in the South Pacific Ocean, is formed as the mighty Pacific plate subducts beneath the smaller, less-dense Philippine plate.  

 

In a subduction zone, some of the molten material—the former seafloor—can rise through volcanoes located near the trench. The volcanoes often build volcanic arcs—island mountain ranges that lie parallel to the trench. The Aleutian Trench is formed where the Pacific plate subducts beneath the North American plate in the Arctic region between the U.S. state of Alaska and the Russian region of Siberia. The Aleutian Islands form a volcanic arc that swings out from the Alaskan Peninsula and just north of the Aleutian Trench.

 

Not all ocean trenches are in the Pacific, of course. The Puerto Rico Trench is a tectonically complex depression in part formed by the Lesser Antilles subduction zone. Here, the oceanic crust of the enormous North American plate (carrying the western Atlantic Ocean) is being subducted beneath the oceanic crust of the smaller Caribbean plate.

Please help! 24 points! please dont just comment for points. I need help. Thank you! Have a blessed day

Answers

Answer:

Job specialization encouraged leisure time, which allowed people to appreciate and develop art, sports, theater, and recreation. Citizens of early cities gained the ability to specialize in their jobs, or to work in certain trades rather than sharing agricultural or other work. Agricultural innovations like irrigation, crop cycling, and harvesting techniques meant that fewer people were needed to work as farmers and laborers. With specialized trades, more citizens in the city could work exclusively in cultural and social trades, developing art and entertainment. Cities became places where cultures developed. These developments pulled new people to cities because the city became the place to learn and experience things that could not be experienced in isolated rural environments.

Compere push and pull factors that drive migration, and give two examples of each.​

Answers

Answer:

Pull factors are the ones that attract migrants (as a strong economy), while push factors are the ones that drive migrants away (like war).

Explanation:

There are numerous different factors that make people migrate from one place to another, but all of them can be put into two broad groups, pull and push factors. The pull factors are factors that attract people to migrate in as these are the factors that offer a better life. The push factors, on the other side, are the factors that make people move away as these are the factors that make life harder.

An example of a pull factor is a strong economy. A strong economy means that the society is well developed and that job opportunities will be abundant, thus there is a chance of improving the economic status and having a better life. An example of a push factor is war. A situation where there is a war means that people feel unsafe and that they may end up losing their lives, or someone from their family and circle of friends. In order to avoid such a scenario, people move away, primarily looking for countries that offer safety.

which part of our body is called food-grinder​

Answers

food grinder is teeth, at least that’s what they taught us

Our body's digestive system is responsible for the digestion and assimilation of food.

The part of the body that is called the food grinder is the mouth or the teeth.

The mouth is called the oral cavity and helps in the physical digestion. It is the first part of the digestive system from where the processing of food starts.

The food first gets into the mouth and by the process of mastication gets broken into smaller molecules.

The food molecule gets mixed with the saliva in the mouth.

There are glands present in the mouth called the salivary gland whose secretion helps in the process of digestion.

Therefore, the mouth is the food grinder.
