weathering and erision unit test
1. What is weathering?
a) The process by which rock is broken down into smaller pieces
b) The process by which sediment is transported by water or wind
c) The process by which minerals are deposited in a new location
d) The process by which fossil fuels are formed
Answer: a) The process by which rock is broken down into smaller pieces
2. What is erosion?

b) Glacier carving out a valley
c) Wind blowing sand dunes across a desert
d) Waves breaking apart cliffs along a coastline
Answer: c) Wind blowing sand dunes across a desert
6. How can humans contribute to both weathering and erosion processes?
a) By planting trees to stabilize soil and prevent erosion
b) By cutting down forests and exposing soil to erosion
c) By building dams and controlling sediment transport in rivers
d) By using sustainable farming practices to reduce soil erosion
Answer: b) By cutting down forests and exposing soil to erosion
7. What is the main difference between weathering and erosion?
a) Weathering breaks down rocks, while erosion transports the broken pieces
b) Weathering transports sediment, while erosion breaks down rocks
c) Weathering is caused by natural processes, while erosion is caused by human activities
d) Weathering and erosion are the same processes
Answer: a) Weathering breaks down rocks, while erosion transports the broken pieces.
