Question

the image shows the great rift valley in africa, an example of a rift valley. which statement best describes how the great rift valley in africa formed? the rift valley formed when the crust pulled apart. the rift valley formed due to subduction. the rift valley formed similarly to an island arc. the rift valley formed at a convergent boundary.

Explanation:

Rift valleys form at divergent plate boundaries, where tectonic plates pull apart, stretching and thinning the crust until it sinks to create the valley. Subduction, island arcs, and convergent boundaries are all associated with tectonic plates colliding, not pulling apart, so those options are incorrect.

Answer:

A. The rift valley formed when the crust pulled apart.
