CKLA Unit 5 Chapter 7

Which of the following is NOT a primary cause of erosion?

• Water
• Wind
• Sunlight
• Gravity

Which of the following is NOT a cause of chemical weathering?

• Plants releasing rock-weathering substances
• Oxygen reacting with iron-containing minerals
• Wind blowing sand against rocks
• Rain mixing with carbon dioxide in the air

What is the primary cause of erosion?

• Water
• Wind
• Gravity
• Ice

How do weathering and erosion work together to shape Earth's surface?

• Erosion causes rocks to break apart, while weathering transports the broken pieces to new locations.
• Weathering and erosion both involve the movement of rocks by wind and water.
• Weathering and erosion are the same process.
• Weathering breaks down rocks, while erosion transports the broken pieces to new locations.

What is the relationship between weathering and erosion?

• Erosion causes weathering
• They are both caused by wind
• Weathering causes erosion
• They are unrelated processes

Which of the following is an example of chemical weathering?

• Wind blowing sand against a rock
• Water dissolving salt in a rock
• Gravity pulling a rock down a hill
• Ice wedging breaking apart a rock

Which of the following is NOT a force that transports sediments?

• Plants
• Gravity
• Ice
• Wind

What are the processes that inevitably change Earth's surface?

• Glaciation and sea level changes
• Plate tectonics and continental drift
• Weathering and erosion
• Volcanic eruptions and earthquakes

What is the process called when water expands as it freezes, pushing outward and enlarging cracks in rocks?

• Ice melting
• Ice wedging
• Ice cracking
• Ice breaking

Which of the following forces is responsible for creating U-shaped valleys in mountain ranges?

• Gravity
• Water
• Wind
• Glaciers
