The Earth's crust is primarily made up of a variety of rocks and minerals. It consists mainly of two types of crust: the continental crust and the oceanic crust.
1. **Continental Crust**: This is thicker and primarily composed of granitic rocks, which are rich in silica and aluminum. Common minerals found in the continental crust include quartz, feldspar, and mica.
2. **Oceanic Crust**: This is thinner and primarily composed of basaltic rocks, which are rich in iron and magnesium. The main minerals found in the oceanic crust include plagioclase, pyroxene, and olivine.
Overall, the crust is made up of about 95% igneous rocks, but it also contains sedimentary and metamorphic rocks. The crust plays a crucial role in supporting life and contains the world's resources, such as minerals, fossil fuels, and fresh water.
