Earth's Surface and Landforms

What are the two types of processes that shape Earth's surface?

• Constructive and destructive

• Weathering and erosion

• Physical and chemical

• Deposition and mass wasting

What is the difference between physical and chemical weathering?

• Physical weathering breaks rocks into pieces, while chemical weathering changes the composition of rocks.

• Physical weathering and chemical weathering have no effect on rocks.

• Physical weathering changes the composition of rocks, while chemical weathering breaks rocks into pieces.

• Physical weathering and chemical weathering are the same process.

Which agents are causes of weathering?

• Water, wind, and ice

• Gravity, erosion, and deposition

• Rain, snow, and hail

• Sunlight, heat, and pressure

What is the main factor that affects the rate of erosion?

• Size of the rock

• Weather and climate

• Topography and type of rock

• Presence of vegetation

Which statement about erosion is true?

• Erosion occurs faster on barren land than on land covered with vegetation.

• Erosion occurs faster on land covered with vegetation than on barren land.

• Erosion occurs faster on land covered with rocks than on land covered with soil.

• Erosion occurs at the same rate regardless of the presence of vegetation.

What happens to the sharp edges of a rock during erosion?

• They disappear completely.

• They become sharper.

• They are broken off.

• They remain the same.

What does the roundness of a rock indicate?

• The size of the rock

• The extent of its erosion

• The type of rock it is

• The age of the rock

What is the difference between a high-energy and a low-energy depositional environment?

• In a high-energy depositional environment, sediment is transported quickly, while in a low-energy depositional environment, even small sediments get deposited.

• In a high-energy depositional environment, sediment is transported slowly, while in a low-energy depositional environment, even large sediments get deposited.

• In a high-energy depositional environment, sediment is transported quickly, while in a low-energy depositional environment, no sediments get deposited.

• In a high-energy depositional environment, sediment is transported slowly, while in a low-energy depositional environment, no sediments get deposited.

What are the agents of deposition?

• Water, wind, and gravity

• Water, wind, and ice

• Weather, climate, topography, and type of rock

• Running water, wind, glaciers, and gravity

What is the location where sediment is deposited called?

• Weathering environment

• Erosional environment

• Depositional environment

• Transportation environment
