Question

select the correct answer. which boundary involves two high - density plates that form deep, narrow trenches along the boundary? a. oceanic - continental convergent boundary b. oceanic - oceanic convergent boundary c. divergent boundary d. transform boundary

Explanation:

Oceanic - oceanic convergent boundaries occur when two oceanic plates (which are high - density) collide. One plate is subducted beneath the other, creating deep, narrow oceanic trenches. In oceanic - continental convergent boundaries, the denser oceanic plate subducts under the less - dense continental plate. Divergent boundaries are where plates move apart, creating rifts. Transform boundaries are where plates slide past each other horizontally.

Answer:

B. oceanic - oceanic convergent boundary
