diverging continental plates collision of tectonic plates movement of glaciers impacts from meteors
I gave my students this multiple choice question: Geologists were examining an area in Africa called the Great Rift Valley. Which geologic event most likely caused the formation of the valley?

Only one answer is correct among these 4 choices:
- diverging continental plates
- collision of tectonic plates
- movement of glaciers
- impacts from meteors

Could you tell me which one is correct?

diverging continental plates
