Earthquake Review

How do mountains form?

• An ocean plate sinks beneath another plate and begins to melt, sending melted rock to the surface, which forms volcanic mountains or islands.
• Hot rock from within the earth risies through ocean floor as plates separate. This forms a volcanic mountain chain, or ridge, on the ocean floor.
• Two continental plates collide, and the land folds and crumples like paper.
• All of the above.

How do P waves effect the surface of the earth.

• moves earth from side to side
• moves earth up and down
