Weathering, Erosion, and Deposition Concepts

The video follows Rocky, a sedimentary rock, as he experiences different types of weathering: organic, mechanical, and chemical. These processes break him down into smaller pieces. Rocky is then moved by erosion and finally deposited in a new location. The video explains how weathering, erosion, and deposition shape the Earth's surface.

What is the process called when rocks, soil, and minerals break down through contact with Earth's atmosphere, water, and life forms?

• Erosion

• Weathering

• Deposition

• Sedimentation

Which type of weathering involves plants breaking up rocks with their roots?

• Chemical weathering

• Mechanical weathering

• Organic weathering

• Thermal weathering

What is mechanical weathering?

• The chemical breakdown of rocks

• The physical breaking of rocks

• The growth of plants on rocks

• The movement of rocks by water

What causes chemical weathering?

• Temperature changes

• Plants growing on rocks

• Water dissolving minerals

• Wind and ice

Which of the following is NOT a cause of weathering?

• Wind

• Ice

• Water

• Fire

What is erosion?

• The process of rocks breaking down

• The chemical alteration of rocks

• The growth of plants on rocks

• The movement of rock pieces to a new location

What happens during deposition?

• Rocks are chemically altered

• Rock pieces are dropped off in a new place

• Rocks are physically broken

• Plants grow on rocks

Which process involves the dropping off of rock pieces in a new location?

• Erosion

• Deposition

• Weathering

• Sedimentation
