Question

1. rift valleys are formed from ____.

○ divergent oceanic boundaries
○ divergent continental boundaries
○ convergent continental boundaries
○ convergent oceanic boundaries

Explanation:

Rift valleys form when continental tectonic plates pull apart (diverge) at a continental divergent boundary, stretching and splitting the crust to create a low-lying, elongated valley. Oceanic divergent boundaries form mid-ocean ridges, while convergent boundaries create features like mountains or trenches, not rift valleys.

Answer:

B. divergent continental boundaries
