What are rocks made of?

    Rocks are made of minerals. There are three types of rocks, igneous, sedimentary and metamorphic. Igneous rocks are made when hot magma cools on the Earth’s surface. Sedimentary rocks are little bits of other rocks that are pushed and cemented together – for example. sand becomes sandstone. Metamorphic rocks are formed when pressure and temperature transform igneous and sedimentary rocks into a new form.

    Rocks are made of minerals and/or mineraloids (mineral-like substances). The mineral and chemical compositions are what classify rocks.
