This document discusses the three main types of rocks: sedimentary, igneous, and metamorphic. Sedimentary rocks form from the accumulation of particles and can be found in places like river banks. Igneous rocks form from the cooling of magma and are located near volcanoes. Metamorphic rocks form from increases in temperature and pressure, such as Michelangelo's famous marble statue of David.
