Moving Ice: Erosion and Deposition in Glaciated Landscapes

What is the process of erosion by glaciers called?

• Snow erosion

• Glacial erosion

• Ice erosion

• Mountain erosion

What are the two types of glaciers?

• Mountain glaciers and valley glaciers

• Tropical glaciers and polar glaciers

• Alpine glaciers and ice sheets

• Frozen glaciers and melting glaciers

How does a glacier erode the land?

• Glaciers erode the land through processes such as plucking, abrasion, and freeze-thaw weathering.

• Glaciers erode the land by volcanic activity

• Glaciers erode the land by wind erosion

• Glaciers erode the land by chemical weathering

What are moraines?

• Moraines are underwater rock formations

• Moraines are desert sand dunes

• Moraines are volcanic eruptions

• Moraines are accumulations of dirt and rocks that have been transported and deposited by a glacier.

What is a drumlin?

• A drumlin is a long, canoe-shaped hill made of glacial till and formed by the movement of a glacier.

• A drumlin is a type of musical instrument used in traditional African music.

How are U-shaped valleys formed by glaciers?

• U-shaped valleys are formed by wind erosion

• U-shaped valleys are formed by tectonic plate movement

• U-shaped valleys are formed by volcanic activity

• U-shaped valleys are formed by the erosive action of glaciers as they move downhill, carving out the valley through processes such as plucking and abrasion.

What is a kettle lake?

• A kettle lake is a type of volcanic crater lake

• A kettle lake is a shallow, sediment-filled body of water formed by retreating glaciers leaving behind depressions in the land.

• A kettle lake is a man-made reservoir

• A kettle lake is a type of hot spring

What is the difference between an esker and a kame?

• An esker is a type of volcano, while a kame is a type of glacier

• The difference between an esker and a kame is that an esker is a ridge, while a kame is a mound or hill.

• An esker is formed by erosion, while a kame is formed by volcanic activity

• An esker is found in deserts, while a kame is found in rainforests

What are the features of deposition left behind by glaciers?

• Coral reefs

• Sand dunes

• Volcanic craters

• Moraines, drumlins, eskers, and erratics are the features of deposition left behind by glaciers.

How do glaciers contribute to the formation of fjords?

• Glaciers have no impact on the formation of fjords

• Glaciers cause the sea level to rise, flooding the land instead of forming fjords

• Glaciers carve out deep valleys which are later filled with seawater, forming fjords.

• Glaciers create deserts instead of fjords
