when an oceanic plate collides with a continental plate at a a boundary, the continental plate may buckle and fold back on itself, forming b.

a
b
this question requires at least one response per row

Explanation:

For A: When oceanic and continental plates collide, it's at a convergent boundary (where plates move toward each other). Divergent is for plates moving apart, transform for sliding past. So A is "convergent".
For B: Convergent boundaries (like oceanic - continental collision) can cause continental plates to buckle and form mountain ranges. Canyons are formed by erosion, rift valleys by divergent boundaries. So B is "a mountain range".

Answer:

A. convergent
B. a mountain range
