Weathering__ Mechanical Weathering Chemical Weathering


 * Weathering occurs when rocks, soil, etc... are broken down. There are two types of weathering- mechanical weathering and chemical weathering. Freezing/Heating, roots, wind, water and ice are mostly responsible for mechanical weathering by acting like hammers, saws, and sandpaper to break down the earth. Chemical weathering occurs when chemicals like carbonic acid eat way at the Earth. In the pictures below, you see the evidence of mechanical weathering in our project. Soil has been broken down. In the picture below is a real life example of weathered rock in the Grand Canyon.





 __Erosion__


 * Erosion occurs when weathered rocks, soil and minerals are MOVED. An easy way of remembering this is to think of it is **e -"ROAD"- sion.** Once again, water, wind and ice are responsible for most erosion as they usually carry away the material they have already weathered.

 __Deposition__


 * The last part of this process is called deposition. This is when the rocks, soil and minerals that have been weathered and eroded and finally dumped. They often create a triangle shape called a "delta" which is a greek letter shaped like a triangle
