The great rift valley was formedin part by:
A)shifting tectonic plates
B)erosion by massive glaciers
my choice is a
A is correct. I refers to an active tectonic area that extends from East Africa across the Red Sea to Syria.
The great rift is caused by spreading apart of the surface which is subsequently further deepened by the forces of erosion. So A is your answer.
