Weathering Erosion and Deposition in Nature

The video tutorial explains the processes of weathering, erosion, and deposition. Weathering involves breaking down rocks into smaller pieces through natural forces like wind, water, and ice. Erosion is the movement of these broken pieces, or sediments, from one place to another by water or wind. Deposition occurs when these sediments settle in a new location, forming features like sand dunes and deltas. The video provides examples and visual explanations to help understand these geological processes.

What is the process called when rocks and minerals break down into smaller pieces?

• Deposition

• Sedimentation

• Weathering

• Erosion

How does water contribute to the weathering of rocks?

• By smoothing rocks through constant flow

• By carrying sediments downstream

• By depositing minerals

• By freezing and expanding in cracks

What natural force is responsible for making rocks smooth over time?

• Wind

• Earthquakes

• Water

• Ice

How do glaciers contribute to the weathering of rocks?

• By causing landslides

• By depositing sediments

• By grinding rocks as they move

• By melting and forming rivers

What happens when water freezes in the cracks of rocks?

• It deposits minerals

• It breaks the rock apart

• It smooths the rock surface

• It causes the rock to expand

What is erosion?

• The formation of new rocks

• The settling of sediments in a new location

• The carrying of sediments from one place to another

• The breaking down of rocks

Which natural force is most likely to cause erosion in a desert?

• Earthquakes

• Wind

• Water

• Ice

What is deposition?

• The dropping of sediments in a new place

• The breaking down of rocks

• The carrying of sediments

• The formation of glaciers

How are sand dunes formed?

• By earthquakes shifting the ground

• By wind blowing sand and depositing it

• By water depositing sediments

• By ice expanding in cracks

What is a delta?

• A process of erosion

• A landform created by deposited sediments at a river's mouth

• A type of rock formation

• A type of weathering
