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:

The Great Rift Valley formed due to tectonic forces. When the Earth's crust is pulled apart (divergent boundary), it creates rift valleys. Subduction occurs at convergent boundaries (not relevant here). Island arcs form at subduction zones (ocean - ocean convergence). Convergent boundaries involve plates coming together, which is not the case for rift valleys. Rift valleys form at divergent boundaries where the crust is stretched and pulled apart.

Answer:

The rift valley formed when the crust pulled apart.
