Weathering Erosion and Deposition

How does freezing water cause the weathering of rocks?  The freezing water—

• keeps the rocks in place

• makes the rocks last longer

• expands cracks and breaks rocks

• causes rocks to fall in landslides

The process that breaks down rocks and other materials on Earth's surface is called

• weathering

• erosion

• soil conservation

• decomposition

The natural chemical or physical processes that breaks down rock on Earth's surface.

• weathering

• erosion

• deposition

• jackhammering

The process by which water, ice, wind or gravity moves weathered rock and soil from one place to another.

What is sediment?

• the process of rocks being broken down and carried away

• bits of rock, sand, and silt caused by the weathering of rocks

• the top layer of the soil

• decaying plant or animal material 

This type of weathering occurs when rocks weaken then break down due to chemical changes in the composition of the rock.
