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

• mechanical weathering

• chemical weathering

• erosion weathering

• deposition

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

• weathering

• erosion

• deposition

How is mechanical weathering different from chemical weathering?

• Chemical weathering happens over much shorter time frame than mechanical weathering.

• Chemical weathering changes the chemical composition of rocks; mechanical weathering does not.

• Chemical weathering occurs only in tropical climates; mechanical weathering occurs only in cool climates.

• Chemical weathering occurs only in the mountains; mechanical weathering occurs only on flat land.

A metal statue slowly turning green after years of being outside is an example of:

• mechanical weathering

• chemical weathering

What is the BEST explanation for what will most likely occur at this type of plate boundary?

• Mountains will form because there is compression and rock folding.

• Thermal vents will form because of magma flowing up under high pressure.

• Volcanic eruptions will occur because the plates slide paste each other.

• Earthquakes will occur when the two different plates slide pass each other.
