What is Weathering?

• The mechanical and chemical processes that break down rock on Earth’s surface.

• The process of weathering that breaks down rock without changing its composition or chemical makeup.

• The process of weathering that breaks down rock by the chemical reaction between rock and the chemicals in air and water.

• The process of predicting the weather of a given place or area.

What is Erosion?

• The mechanical and chemical processes that break down rock on Earth’s surface.

• The laying down, or setting of eroded material.

• The moving of weathered material , or sediment, from one location to another.

• a large mass of ice that moves slowly across Earth’s surface
