1. Weathering Project By: Joe Heitmeier

2. Biological Weathering: Cracked Garage Concrete This is biological weathering because it was cracked by a car driven by a human.

3. Physical Weathering: Weeds in Sidewalks This is physical weathering because weather such as sitting water cause the mold to form in the crack.

4. Physical Weathering: Road Cracks This is physical weathering because the concrete was heated and cooled over and over again so it cracked.

5. Biological Weathering: Run Down Trail This is biological weathering because hikers or people have walked over this patch of ground and caused it to be weathered.

6. Chemical Weathering: Buildings Dissolving This is chemical weathering because chemicals caused the brick to rot and then crumble.

7. Chemical Weathering: Rusting Metal This is chemical weathering because the metal on the pot mixed with a chemical and caused it to rot.
