when a glacier pulls chunks of rock from the bedrock as it moves over it

when rocks and debris carried by a glacier scrape and wear away the surface beneath it

a valley reshaped by glacial erosion into a U-shape

accumulation of unsorted debris, such as soil and rock, deposited by a glacier

Glacial landforms resulting from erosion and deposition

Geography

This unit, comprising of three variants, teaches pupils about processes and landforms associated with coastal, river and glacial landscapes. Pupils will learn about the formative processes involved in creating distinctive landforms and of the need for management.

Coastal, river and glacial landscapes

a glacier pulls chunks of rock from the bedrock as it moves over it

rocks and debris carried by a glacier scrape and wear away rock

an accumulation of unsorted debris, deposited by a glacier

Match the key words to their definitions.

A {{}} is a bowl-shaped hollow found on the upper slopes of glaciated valleys, often containing a small lake (tarn/cwm) after glaciation.

Snow collects in a sheltered hollow on the side of a mountain. The snow doesn't

melt in the summer because it is high up, sheltered and cold. Every winter, more

snow collects in the hollow. This is compacted to ice. The back wall of the

corrie gets steeper due to freeze-thaw weathering and plucking. The base of

the corrie becomes deeper due to abrasion. Rotational slip increase erosion at

the base of the corrie. At the front of the corrie, erosion decreases

and a rock lip forms. After the glacier has melted a lake forms in the hollow.

Which of the following are glacial landforms created by deposition?

The wearing away of pieces of rock, soil or other solid materials

When material is deposited or left behind

To move objects or people from one place to another

A large body of water that flows over land

A large mass of ice that moves slowly over land

A type of rock formed by volcanic activity

The break-up of rocks caused by water regularly freezing and thawing

The movement of rock from one place to another

The last {{}} in the UK took place around 18 000 years ago. During this time, temperatures remained low throughout the year and ice sheets and glaciers covered the north of the UK.

Widening existing V-shaped river valleys into U-shaped valleys

Glacial erosion is very powerful and has a range of effects, including:

Glaciers move slowly, transporting material called glacial {{}} in different ways depending on its position within the ice.
