​Weathering, Erosion, & Deposition!

​Weathering, Erosion, & Deposition!

Learning Objective

I can explain the difference between weathering, erosion, and deposition and tell how each one changes the land.

KNOWLEDGE CHECK!

Weathering is when rocks are broken down into smaller pieces over time by things like water, wind, ice, or plants.

Erosion is when water, wind, ice, or gravity move broken pieces of rock and soil from one place to another.

Multiple Choice

What is the process of breaking down rocks

• weathering

• erosion

• depostion

New word alert!

Deposition!

Deposition

Deposition is when the moved rocks, sand, or soil are dropped and settle in a new place after being carried by water, wind, ice, or gravity.

• It happens when erosion stops or slows down.

• The material that gets dropped is called sediment (sand, soil, rocks).

• Deposition can build new land over time.

• Deposition is why we see sandbars, beaches, and deltas.
