| 2.Describe the weathering processes of each Chemical weathering agent. | Common agents of Chemical Weathering are water,weak acids,and air. 1. Rain, weak acids, and air chemically weather granite. |
| 3.Describe the weathering processes of each Mechanical Weathering agent. | Agents of Mechanical Weathering include ice,wind,water,gravity,plants and even animals. What the ice does is the alternative freezing and thawing soil and rock, called frost action,is a form of mechanical weathering. |
| 4. What is the most important and most common agent of Chemical Weathering? Why? | The most important and most common agent of Chemical Weathering is water because if you drop a cube into a glass of water, the sugar cube will dissolve after a few minutes. This process is an example of chemical weathering. |
| 5. What is the difference between weathering, abrasion, erosion, and deposition? | Weathering is the breaking down of rock into smaller pieces, |
