Chemical and Mechanical Weathering

What can cause chemical weathering?

• Oxygen

• Carbon dioxide

• Acid rain

• All of these

Substances from decaying plants reacting with minerals in rocks

• Mechanical Weathering

• Chemical Weathering

• Both Mechanical and Chemical Weathering

The type of weathering that is the physical break down of rocks.

• Mechanical

• Ice Wedging

• Roots

• Chemical

• Carbonic Acid

When water enters cracks in rocks and freezes, it expands and breaks the rock apart.
