Glacial Erosion

Plucking

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.

Abrasion

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

Freeze – thaw or frost shattering

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.

This video looks at Glacial Eroison and shows how the landforms are created

The Ice Age in Britain lasted from about one million years ago to about 20 000 years ago. During that time the Northern and Eastern parts of the British Isles were covered in ice. Glaciers were formed which move down valleys with great erosive power. These glaciers carved new scenery.

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

sea erosion
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.

There are three main types of glacial erosion - plucking, abrasion and freeze thaw

# data[].attributes.body
Plucking is when melt water from a glacier freezes around lumps of cracked and broken rock. When the ice moves downhill, rock is plucked from the back wall. Abrasion is when rock frozen to the base and the back of the glacier scrapes the bed rock. Freeze-thaw is when melt water or rain gets into cracks in the bed rock, usually the back wall. At night the water freezes, expands and causes the crack to get larger. Eventually the rock will break away.

Rainfall, and the surface runoff which may result from rainfall, produces four main types of soil erosion: splash erosion, sheet erosion, rill erosion, and gully erosion.

The more sediment that's picked up, the greater the force of erosion. The erosion can smooth out areas that were once rugged and rocky. Glaciers can carry almost anything, and like sandpaper, the sediment just keeps increasing. Glaciers are such a powerful force that they can carve valleys, deposit moraines, or lead to the creation of landforms such as delta

Glacier Erosion

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.

chemical erosion
sheet and rill erosion

Hill slopes are prone to sheet erosion and rill erosion. The amount of hill slope erosion largely depends on how the land is used.

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