The great rift valley in africa is a a. mid-ocean ridge c. convergent boundary b. divergent boundary d. transform boundary

The correct answer from the given choices is "b. divergent boundary".

The Great Rift Valley in Africa is a "divergent boundary".

The Great Rift Valley involves one such tremendous breadth, extending crosswise over a great many miles from Mozambique to the Middle East. Most rift valleys are found undersea; the East African Rift is one of only a handful few situated ashore. Such land-based rift valleys regularly lie where maturing structural plates start to tear far from each other. This partition procedure is known as rifting and is related with the development of divergent plate boundaries.

it sounds like either a or c
