The image shows the Great Rift Valley in Africa, An example of a rift valley.

Which statements BEST describes how the Great Rift Valley in Africa formed?

• The rift valley formed with 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.

What causes the force that pushes magma from the magma chamber through the pipe and vent of a volcano?

• gravity

• water flow

• expanding gases

• convergent boundaries
