12) The drift theory by Alfred Wegner proved this theory.

13)a)Convergent boundary b)Divergent Boundary c)Transform fault 14) This is because when a continent and continent plate hit they create ridges and mountains. 15) Some of the fossils found in those mountains is similar. Also, trees and rock sedimentation is similar. 16) The tectonic plates would stop drifting. It is because of convection that the plates move. 17) It shows how hot the magma inside the earth can be. 18)This is because when tectonic plates move on plate may go under the other. This creates a "hole" on the earths surface. Magma seeps through this hole and hardens quickly. 19) Alot of magma would seep through. 20)Because the destruction can damage the instruments. 21)
