Weathering and Erosion Exam

What is physical weathering?

• The breakdown of rocks through chemical changes.

• The breaking of rock into smaller pieces without changing its chemical composition.

• The movement of weathered material from one location to another.

• The process of laying down or settling eroded material.

Which of the following is an example of chemical weathering?

• Ice wedging

• Plant roots breaking rocks

• Acid rain dissolving limestone

• Animals burrowing

What natural force is responsible for forming dunes and loess?

• Water

• Wind

• Ice

• Gravity

Match the following processes with how glaciers contribute to them.

• Glacial erosion

• By moving rocks and soil downhill

• Glacial abrasion

• By carving landscapes and leaving behind valleys and ridges

• Glacial plucking

• By carrying sediments and shaping valleys

• Glacial transportation

• By moving fine sediments

What is deposition?

• The breakdown of rocks through chemical changes

• The movement of weathered material from one location to another

• The process of laying down or settling eroded material

• The breaking of rock into smaller pieces without changing its chemical composition

The process called when fast-moving water erodes land is (a)  

• Deposition
• Stream Erosion
• Coastal Erosion
• Groundwater Erosion

Match the following types of erosion with their descriptions.

• Erosion involving the movement of water through soil and rock underground.

• Groundwater Erosion

• Erosion caused by flowing water in rivers and streams.

• Wind Erosion

• Erosion caused by the movement of air over the surface.

• Coastal Erosion

• Erosion involving waves and currents reshaping shorelines.

• Stream Erosion

What is the role of wind in changing the Earth's surface by grinding and polishing rock surfaces?
