Unit 2 Test Review: Rocks & Processes

The formation of soil is primarily a result of:

• weathering and biological activity

• stream deposition and run off

• precipitation and wind erosion

• stream erosion and mass movement

Breaking rocks down without changing what the rock is made of is called:

• Mechanical Weathering

• Deposition

• Chemical Weathering

• Erosion

Cracks in rocks widen as water in them freezes and thaws. How does this affect the surface of the Earth?

• It limits the exposure of rocks to acid precipitation.

• It reduces the rates of soil formation.

• It exposes rocks to increased rates of erosion and weathering.

• It changes the chemical composition of the rocks.
