Erosion

Based on the information presented in the video, what would be a simple way to prevent erosion?

• Blocking the wind

• Planting trees

• Preventing rainfall

• Preventing the flow of rivers

Which term BEST describes the rate at which glacial erosion takes place?

• Quick

• Short

• Slow

• Sudden

Why is it hard to see glacial erosion in action?

• Because glaciers are so big

• Because light from glaciers refracts too much

• Because glaciers move very, very slowly

• Because glacial erosion is usually very subtle

Choose TWO descriptions below that represent Erosion.

• Rain washing away dirt from a hillside

• Water getting in cracks of rocks, freezing, and breaking them

• Wind hitting the top of a mountain for thousands of years creating arches.

• Waves moving sand from one place to another

When a glacier moves, it picks up and carries the rocks with it. These rocks are weathered by:

• abrasion

• exfoliation

• thermal expansion

• hydrolysis
