Exploring Weathering, Erosion, and Deposition

The video explains the process of weathering, which breaks down rocks into smaller pieces through agents like water, ice, wind, plants, and temperature changes. It also covers erosion, the movement of weathered materials, and deposition, where these materials are deposited in new locations. The video highlights how these processes shape the Earth's surface over time.

What is the most powerful agent of weathering?

• Sun

• Water

• Wind

• Plants

How does water cause physical weathering in rocks?

• By flowing over them

• By freezing and expanding in cracks

• By causing chemical reactions

• By soaking the rocks

What role do plants play in weathering?

• They produce acids that dissolve rocks

• They provide shade to rocks

• Their roots grow into cracks and break rocks

• They absorb water from rocks

What is erosion?

• Breaking down of rocks into smaller pieces

• Freezing of water in rocks

• Transportation of weathered materials

• Growth of plants in rocks

How do glaciers contribute to erosion?

• By carrying rocks and soil as they move

• By melting and causing floods

• By freezing the ground beneath them

• By providing water for rivers

What happens to the materials carried by a river?

• They sink to the riverbed

• They are deposited at the river's mouth

• They evaporate

• They are absorbed by plants
