Answer:

The answer is below

Step-by-step explanation:

Plates are composed of the Earth’s crust and upper mantle. These plates are constantly moving at a very slow rate (in small centimeters every year). The movement of the plates causes them to collide with each other thereby forming volcanoes.

The Mariana Trench and the large number of volcanoes west side of the Pacific Plate are as a result of the collision of two plates (the larger Pacific plate sliding beneath the smaller, less-dense Philippine plate).
