answer.

Answer 1

Subduction is the process at convergent plate boundaries where the old crust disappears into trenches as new crust is formed.

Step-by-step explanation:

Subduction is the process at convergent plate boundaries where the old crust disappears into trenches as new crust is formed. It occurs when tectonic plates collide and one plate, usually oceanic, is forced beneath the other plate into the mantle.

For example, when the Pacific Plate collides with the North American Plate, the Pacific Plate subducts beneath the North American Plate, forming the Cascadia Subduction Zone along the west coast of North America.

Subduction zones are associated with various geological phenomena such as volcanic activity, earthquakes, and the formation of mountain ranges.
