The document discusses the composition of the Earth's solid parts and the classification of rocks. Rocks are made of one or more minerals and are classified based on their origin as igneous, sedimentary, or metamorphic rocks. Igneous rocks form from cooling magma, sedimentary rocks form from particles of other rocks and minerals that have been eroded and deposited over time, and metamorphic rocks form from existing rocks undergoing changes due to heat and pressure in the Earth's crust and mantle.
