18
Q

Describe 3 processes or mechanical weathering

A

Ice wedging - water seeps into cracks and freezes and then expands breaking the rock
Temperature extremes- rocks expand in heat and contract in cold
Living things- trees force rocks to split

19
Q

Describe 3 processes of chemical weathering

A

Hydrolysis- chemical interaction with water on rocks
Carbonation - carbonic acid and other minerals form substances
Oxidation - chemicals combing with oxygen (rust)

20
Q

3 factors that determine how fast rocks weather
