In what formation are Mariana trench plates involved?

Geography
1 answer:
NeTakaya3 years ago
4 0

Answer:

Subductio zone

Explanation:

The Mariana trench is a result of the convergent plate boundary between the Filipino plate and Pacific plate, creating a subduction zone. The Filipino plate is not a large one, but still the much larger Pacific plate is subducting below it. The reason for this is that the Pacific plate is denser, heavier, lower. At the boundary itself, the Pacific plate moves below the Filipino plate, slowly getting into the mantle layer and getting melted and destroyed. The subduction zone though makes a large gap between the two plates, a gap that is constantly under immense pressure and experiences constant geological activity. This gap is filled with the ocean water, and it is actually the deepest place on the surface of the Earth with over 11 km bellow sea level. The name of it comes from the island chain next to the subduction zone, the Mariana Islands, thus it is called Mariana trench.

According to the Tenth Amendment, the powers of________ are limited to only
Travka [436]

Answer:

the federal government

Explanation:

The Tenth Amendment to the United States Constitution restricts the federal government's powers to those specified in the Constitution and its amendments, leaving all other powers to the states and "the general population." This is significant in light of the fact that the federal government has only recently defined forces, which are limited to those "recorded" in the Constitution, otherwise known as identified forces. Without that constraining modifier, the federal government, specifically Congress, has been held to have unenumerated powers under what is known as the "necessary and proper" provision (Article I, Section 8), which allows Congress to make any laws that are necessary and proper to carry out the listed obligations, those that are specifically named. The manner in which the crucial and valid provision was integrated has been deciphered to imply that it encompasses many powers.

Answer:

C. the movement of the Earth's plates

Explanation:

The plates can be thought of like pieces of a cracked shell that rest on the hot, molten rock of Earth's mantle and fit snugly against one another. The heat from radioactive processes within the planet's interior causes the plates to move, sometimes toward and sometimes away from each other.This movement is called plate motion, or tectonic shift.
