• Freezing

• Weathering

• Erosion

Which type of weathering is caused by animals?

• Chemical weathering

• Biological weathering

• Erosion

• Physical weathering

What are the main agents of erosion?

• plants, animals, fungi, and bacteria

• fire, air, earth, and metal

• sun, moon, stars, and planets

• water, wind and ice

How does weathering affect the Earth's surface?

• It has no impact on the Earth's surface

• It causes rocks and minerals to multiply on the Earth's surface

• It breaks down rocks and minerals on the Earth's surface.

• It creates new landforms on the Earth's surface

What landform is created by the erosion of a river?

• Desert dune

• River valley or river canyon

• Mountain peak

• Glacier

What can be done to prevent erosion?

• Digging deeper trenches

• Pouring concrete over the soil

• Planting trees and vegetation

• Removing all vegetation

What form of weathering is often responsible for the formation of caves?

• Volcanic weathering

• Physical weathering

• Chemical weathering

What landform is created by the erosion of a coastline?

• Canyon

• Beach or coastal plain

• Desert

• Mountain

How does water contribute to erosion?

• By creating new land formations

• By carrying sediment and debris, wearing away the land surface over time.

• By increasing the stability of soil

• By reducing the flow of rivers

What are the effects of weathering on human-made structures?

• Weathering has no effect on human-made structures

• Weathering can cause corrosion, erosion, and deterioration of human-made structures.

• Weathering leads to strengthening of human-made structures

• Weathering causes human-made structures to become more resistant to damage
