1. Rocks are made up of minerals and can be found deep underground in mines or near the surface in quarries. 2. Minerals have unique properties like hardness, lustre, and color that allow them to be identified. They are used to make construction materials, obtain metals, and create jewelry. 3. Soil is formed over long periods of time as rocks are broken down by weathering and mixed with decaying matter. It is made up of layers with different materials and must be protected to support plant growth.
