Glaciers: When big moving islands of ice are in the ocean


Rapid process erosion: Erosion that happens very fast, like  when a earthquake strikes and some land disappears.


Slow process erosion: When wind erosion hits a rock, a very slow progress happens until the rock is shaped like something else.


Tsunami: When an earthquake happens in the middle of the ocean, very soon a big, giant, humongous wave hits the shore, that is a tsunami.
