Glacier Knowledge

What is glacial erosion?

• The process by which glaciers carve and shape the land through the movement of ice and the abrasion of rocks and sediment.

• The process by which glaciers deposit sediment and create new landforms.

• The process by which glaciers cause earthquakes and volcanic eruptions.

• The process by which glaciers melt and form lakes and rivers.

Which of the following is an example of glacial erosion?

• Formation of sand dunes.

• Formation of canyons.

• Formation of V-shaped valleys.

• Formation of U-shaped valleys

What is glacial deposition?

• The process by which glaciers form and grow due to the accumulation of snow and ice.

• The process by which glaciers deposit sediments and rocks as they move and melt.

• The process by which glaciers change shape and size due to the effects of climate change.

• The process by which glaciers erode and remove sediments and rocks as they move and melt.

What are U-shaped valleys?

• Valleys formed by rivers.

What are cirques?

• Large bodies of water surrounded by land.

• Bowl-shaped hollows at the head of a glacier valley

• Steep cliffs formed by erosion.

• Deep cracks in the Earth's crust.

What are moraines?

• Accumulations of unconsolidated debris deposited by glaciers

• Erosional features formed by wind

• Deposits of sediment carried by rivers

• Layers of volcanic ash

What are drumlins?

• Elongated hills formed by glacial ice movement

• Small mounds formed by volcanic activity.

• Steep cliffs formed by erosion.

• Deep valleys carved by rivers.

What are eskers?

• Small, round hills formed by volcanic activity.

• Large, flat areas of land covered in ice.

• Steep, narrow valleys formed by glacial erosion.

• Long, winding ridges of sand and gravel formed by meltwater streams beneath glaciers
