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

The correct answer is option (b).

Explanation:

Divergent boundary is a feature of tectonic plates in which two plates moves away from each other. The Great Rift Valley in Africa is an example of it which runs through Kenya from north to south.The eastern branch is towards Ethiopia and western branch is towards Tanzania.

Hence, the correct answer is option (b).

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
