Erosion in the Sea also occurs. The salts and other chemicals can erode weak rocks on the coast, such as limestone and chalk. The eroded materials are carried up the shore by the means of a longshore drift

Waves crashing against the shore can create air pressure inside cracked rocks, that can eventually break them. Furthermore, if rocks, pebbles or sediment is carried in the waves, they can smash up against the shore and erode it even more.

Ice erosion, besides that of hail, comes mostly in the form of glacier erosion. Glaciers are giant bodies of ice that can pick up huge pieces of rock, some even as big as houses. A combination of the water, ice, and picked up sediment, create a powerful eroding machine.

Sheet erosion occurs when a thin layer of topsoil is removed over a whole hillside paddock—and may not be readily noticed.

Glaciation is the study of ice and its impact on the environment.

As the glacier moves, friction causes the bottom of the glacier to melt this water freezes into joints in the rock. When the glacier moves again the rock is pulled away or ‘plucked’ from the base of the valley.

Rock pieces that have been plucked away and carried by the glacier (moraine) act like sandpaper scraping away at the valley bottom and sides.

Water enters into cracks in the rock over time it freezes and repeatedly thaws putting large amounts of pressure on the rock – eventually this will force the rock to break apart or shatter.
