Erosion and Weathering

What is weathering?

• The breaking down of rocks into smaller pieces called sediment.

• The movement of sediment from one place to another.

• When moving sediment is deposited in a new location.

As a river quickly flows, it carries many rocks and sediment. These rocks and sediment scrape against each other. How will they change over time?

• They will get heavier.

• Their mass will increase.

• They will get larger.

• They will get smaller.
