Chunky Weathering and ErosionEarth’s surface breaks into chunks and the chunks move.

Page 2: Chunky Weathering and Erosion

The breakdown of rocks at or near Earth’s surface is called?

weathering

Page 3: Chunky Weathering and Erosion

What are the two types of weathering?

Physical and chemical

Page 4: Chunky Weathering and Erosion

Which type of weathering actually changes a rock’s composition?

chemical

Page 5: Chunky Weathering and Erosion

What is it called when ice expands in a crack in a rock?

Ice wedging or frost action

Page 6: Chunky Weathering and Erosion

Abrasion is a form of which type of weathering?

physical

Page 7: Chunky Weathering and Erosion

When limestone bedrock dissolves due to chemical weathering it can form?

Sinkholes or caverns

Page 8: Chunky Weathering and Erosion

An example of biological weathering would be . . .

Plant root in rock

Page 9: Chunky Weathering and Erosion

The weathering of bedrock ultimately forms this important material.

soil

Page 10: Chunky Weathering and Erosion

The driving force of most erosion is?

gravity

Which of the following are considered mass movement?

soil creeplandsliderock fall

They’re all mass movement

Page 12: Chunky Weathering and Erosion

V-shaped valleys are carved by?

Rivers and streams

Page 13: Chunky Weathering and Erosion

True or false – rivers produce sharp edged sediments

False – they produce rounded sediments

Page 16: Chunky Weathering and Erosion

The area of land drained by a stream is called a?

watershed

Page 17: Chunky Weathering and Erosion

What type of erosion created this formation?

wind

Page 18: Chunky Weathering and Erosion

Glaciers carve what shape valleys?

Page 19: Chunky Weathering and Erosion

What arrangement of sediments are left by glaciers?

Unsorted

Page 20: Chunky Weathering and Erosion

What other evidence of glaciation might be found in a U-shaped valley?

Striations or erratics

Page 21: Chunky Weathering and Erosion

This glacial formation is called a?

drumlin
