Question

4. Describe what happens when:

Answer 1

When two plates carrying oceanic crust collides, islands and volcanoes are formed.

When two plates carrying continental crust collide, it makes mountain ranges and valleys.

When a plate carrying oceanic crust collided with a plate carrying continental crust collides, the oceanic plate subsides under the continental one due to the density of the two, and makes trenches and mid-ocean ridges.
