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.

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

The star on the following map is pinpointing what geographical feature?
The Ural Mountains
The Caucasus Mountains
The Sayan Mountains
The Caspian Sea
Answer:
Correct answer is The Ural Mountains.
Explanation:
The Caspian Sea is not correct answer as sea is marked with blue color.
The Sayan Mountains are more to the east, closer to the border with Mongolia.
The Caucasus mountains are between Caspian and Black Sea and that also is not correct.
Therefore, the only correct answer is Ural, as this mountains are also natural border between Europe and Asia.
DDT is used to kill mosquito caterpillar that carries malaria but it affected the ecological balance and the whole food chain in natural ecosystem. houseflies died when they fed on the dead caterpillars. This in turn killed little lizards when they fed on dead houseflies. Finally, the cats that eat the dead lizards died of ddt poisoning. The effect was invasion of dwelling with more and more rats raiding the house for food and carrying the plague.

and low temperature.
high
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.

Using complete sentences, describe six innovations that have contributed to the mechanization of agriculture since theIndustrial Revolution.
Please help! 24 points! please dont just comment for points. I need help. Thank you! Have a blessed day
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.
Explanation:
poggers!
Answer:
Innovations since the Industrial Revolution that have contributed to the mechanization of agriculture include refrigeration, mechanical threshers and harvesters, airplanes, electricity, irrigation machines, and the use of computers.
Explanation:
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..
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.
An earthquake that occurs in a region underlain by igneous rocks is more likely to experience large-magnitude earthquakes than an area underlain by sedimentary rocks because:

around the world as a result of devolution?
(A) French-speaking people
(B) Spanish-speaking people
(C) Urban women
(D) Indigenous people
(E) Recent immigrants from
Answer:
(D) Indigenous people
Explanation:
Devolution means that power is delegated to the lower stances of the governance, such as local and regional institutions, instead of being centralized by the president, cabinet, and the other leaders. This way, minor communities can take charge of their own organizing, resources, and regulations the way they find most fitting.
Devolution is extremely helpful for indigenous people. As indigenous communities, like Native Americans or Aborigines, tend to live in their own groups and their own land, devolution means they get to control the land and resources so they would maximize the benefit. They can also adopt the governance according to their traditional codexes and beliefs.
