Glaciers and Landforms

What is glacial erosion and how does it contribute to the formation of landforms?

• Glacial erosion is a slow process that has no effect on the formation of landforms

• Glacial erosion is caused by volcanic activity and has no impact on landforms

• Glacial erosion is the process of glaciers moving and scraping the land, which contributes to the formation of landforms through processes such as plucking, abrasion, and deposition.

• Glacial erosion is the result of wind erosion and contributes to the formation of deserts

Explain the process of glacial deposition and provide examples of landforms created by it.

• Deserts, plains, and beaches

• Volcanoes, mountains, and hills

• Moraines, drumlins, and eskers are examples of landforms created by glacial deposition.

• Canyons, plateaus, and valleys

How do glaciers impact landscapes in terms of shaping valleys and creating fjords?

• Glaciers erode and carve valleys, and create fjords through their movement and erosion.

• Glaciers cause the formation of volcanoes and mountains

• Glaciers create deserts and arid landscapes

• Glaciers have no impact on shaping valleys and creating fjords

Discuss the role of glaciers in the formation of moraines and drumlins.

• Glaciers erode and transport material, depositing it as moraines and drumlins.

• Glaciers have no role in the formation of moraines and drumlins

• Moraines and drumlins are formed by volcanic activity, not glaciers

• Moraines and drumlins are man-made structures, not formed by natural processes

What are the different types of glacial erosion features and how are they formed?

• Mountains, valleys, and plains. Formed through tectonic plate movement and erosion by rivers and streams.

• Lakes, rivers, and waterfalls. Formed through sedimentation and erosion by ocean waves and currents.

• Deserts, canyons, and plateaus. Formed through volcanic activity and erosion by wind and water.

• Cirques, aretes, horns, and U-shaped valleys. Formed through plucking, abrasion, and freeze-thaw weathering.

Describe the formation of eskers and kames as a result of glacial deposition.

• Formation by wind erosion

• Formation by volcanic activity

• Glacial deposition of sediment by meltwater streams

• Formation by tectonic plate movement

Explain the concept of glacial striations and their significance in understanding glacial erosion.

• Glacial striations indicate the presence of fossilized remains

• Glacial striations are caused by volcanic activity

• Glacial striations are scratches or grooves on bedrock caused by the movement of glaciers. They are significant in understanding glacial erosion as they indicate the direction of ice flow and the amount of pressure exerted by the glacier on the underlying rock.

• Glacial striations have no significance in understanding glacial erosion

Discuss the formation of cirques and aretes as a result of glacial erosion.

• Cirques and aretes are formed by volcanic activity.

• Glacial erosion leads to the formation of deserts and canyons.

• Glacial erosion leads to the formation of cirques and aretes.

• Glacial erosion has no impact on the formation of landforms.

How do glaciers contribute to the formation of U-shaped valleys and hanging valleys?

• U-shaped valleys are formed by volcanic activity and hanging valleys are formed by earthquakes

• Glaciers have no impact on the formation of U-shaped valleys and hanging valleys

• Glaciers create U-shaped valleys by depositing sediment and hanging valleys by melting completely

• Glaciers carve out U-shaped valleys through erosion and leave behind hanging valleys when they retreat.

Explain the impact of glaciers on the formation of glacial lakes and outwash plains.

• Glaciers have no impact on the formation of glacial lakes and outwash plains

• Glaciers cause the land to rise instead of forming lakes and plains

• Glaciers create deserts instead of lakes and plains

• Glaciers carve out basins and depressions in the landscape, which can fill with water to form glacial lakes. As glaciers melt, they deposit sediment and create outwash plains.
