5 Things to know about Weathering & Erosion
1. Weathering is the breakdown of rock chemically and physically.

Chemical weathering (acid rain, chemical reactions O2, CO2 and H2O)

Physical weathering can be aided by: plant roots, ice (frost wedging like what
occurs in primary succession with lichens)
2. Erosion is the movement of weathered sediments altering the surface of the land.
3. Agents of erosion are wind and water
Rock Cycle- weathering and erosion are important to creation of sedimentary rock
4. Weathering- breaks down rocks into loose material, aka sediments.
5. Erosion- moves the sediment to a location conducive to creation of sedimentary rocks
