  3. 3. Physical Weathering Physical weathering is when a rock is cut without changing its minerals. Rocks such as granite, limestone, and even obsidian can be cut by physical weathering.
  4. 4. Chemical Weathering Chemical weathering is when the minerals inside a rock are changed. The picture above is an example of this. This is an example of chemical weathering.
  5. 5. Exfoliation Exfoliation is when a mountain is peeled like an onion by a glacier or other large natural form. Half Dome was formed by exfoliation. Half Dome in Yosemite
  6. 6. Abrasion Abrasion is when sand gets into the cracks inside a rock and as the wind blows, slowly breaks down the rock into amazing formations. This is a diagram about abrasion.
