The correct answer is D. All of the above.
Oceanic-oceanic convergence occurs when two oceanic plates collide. The denser plate will subduct under the less dense plate, and the resulting magma will rise to form volcanoes.
Oceanic-continental convergence occurs when an oceanic plate collides with a continental plate. The denser oceanic plate will subduct under the less dense continental plate, and the resulting magma will rise to form volcanoes. The continental plate will be pushed up and folded, forming mountains.
Continental-continental convergence occurs when two continental plates collide. The plates will be pushed up and folded, forming mountains. The collision of the plates will also cause the crust to thicken, and the resulting pressure may cause the crust to melt, forming magma.
Here is a diagram that shows the three types of plate convergence:
The diagram shows the three types of plate convergence: oceanic-oceanic convergence, oceanic-continental convergence, and continental-continental convergence. The arrows show the direction of plate movement. The denser plate is shown in blue, and the less dense plate is shown in red. The resulting magma is shown in yellow.
I hope this helps!
