Question

what geological features are typically formed at continent - continent convergent boundaries? oceanic trenches rift valleys mountain ranges

Explanation:

At continent - continent convergent boundaries, two continental plates collide. Since both plates are relatively buoyant, neither is subducted. Instead, the crust is compressed and uplifted. Oceanic trenches form at ocean - continent convergent boundaries (where an oceanic plate is subducted). Rift valleys form at divergent boundaries (where plates move apart). Mountain ranges, like the Himalayas (formed by the collision of the Indian and Eurasian plates), are typical of continent - continent convergent boundaries.

Answer:

Mountain ranges
