  • How Do Rocks Break Down?

    Sedimentary, Metamorphic, and Igneous Rocks begin breaking down from 3 types of stress: Physical, Chemical, and Biological.
  • Chemical Weathering

    Chemical Weathering
    One example of chemical weathering is water. These rocks are decomposed or decayed from the water.
  • Biological Weathering

    Biological Weathering
    One example of biological weathering is when trees grow in between a rock and break it apart.
  • Physical Weathering

    Physical Weathering
    An example would be this arch. A physical change means its chemical components were not changed.

  • Soil, Erosion, or Both?

    Soil, Erosion, or Both?
    Once the rocks have continued to break down into smaller and smaller pieces, two different things can happen. They can be turned into soil or they can participate in erosion and be moved somewhere else or they can be moved by erosion and then settle as soil.
