Question

1. a collision between two pieces of continental crust at a converging boundary produces a

deep ocean trench
rift valley
mid ocean ridge
mountain range

Explanation:

When two continental crusts collide at a converging boundary, they push against each other. Since continental crust is relatively thick and buoyant, it cannot be subducted (unlike oceanic - continental or oceanic - oceanic convergence where one plate can be subducted). The force of the collision causes the crust to buckle, fold, and uplift, forming mountain ranges.

• A deep - ocean trench is formed at an oceanic - continental or oceanic - oceanic subduction zone.
• A rift valley is formed at a divergent boundary (where plates are moving apart).
• A mid - ocean ridge is also formed at a divergent boundary in the ocean.

Answer:

Mountain range
