Glaciation 1

An extensive area of land regarded as being visually and physically distinct.

• Arete

• Landscape

• Plucking

• Moraine

Erosion caused by rocks and boulders in the bass of the glacier acting like a giant file scratching and scraping the rocks below.

• Hanging Valley

• Outwash

• Plucking

• Abrasion

A type of erosion where melt water in the glacier freezes onto rocks, and as the ice moves forward it plucks or pulls out large pieces along the rock joints.

• Deposition

• Abrasion

• Plucking

• Transportation

An unsorted mixture of sand, clay and boulders carried by a glacier and deposited as ground moraine over a large area.

• Snout

• Till

• Outwash

• Erratic

This occurs when the ice moves in a circular motion. This process can help to erode hollows in the landscape, and deepen hollows into bowl shapes.

• Rotational Slip

• Slumping

• Bulldozing

• Glacier

Ice pushes material of all shapes and sizes as it moves slowly forward.

• Ploughing

• Shoving

• Bulldozing

• Barging

It occurs in cold climates when temperatures are often around freezing point and where exposed rocks contain many cracks. Water enters the cracks during the warmer day and freezes during the colder night.

• Plucking

• Freeze-thaw Weathering

• Freeze-thaw Erosion

• Abrasion

What are warmer periods of time that are not ice ages known as?

• Glacial

• Intergalactic

• Interglacial

• Hot

Glaciers form during ice ages and more snow is added to the glaciers high up in the mountains. This is known as..

• Ablation

• Accumulation

• Blizzard

• Snow fall

What is the front part of a glacier called?

• Nose

• Beak

• Snout

• Peak
