Weathering

Exposure to rain and oxygen causes the metal minerals in rocks to rust and fall apart.  This is an example of:

• mechanical weathering

• chemical weathering

The definition of weathering is...

• the breakdown of rock over time into smaller pieces

• the breakdown of rocks over an emotional breakup

• the breakdown of a car on the side of the road

• the breakdown of rock over the breakup of a favorite rock group

This shows what kind of weathering?
