About this document
Overview of Rock Types and Formation by Caleb Cagna-an is a document available to read on EtoBox.
There are three main types of rocks: igneous, sedimentary, and metamorphic. Igneous rocks form from cooling magma either underground or after volcanic eruptions. Sedimentary rocks form from the compression of materials like sand and shells over long periods of time. Metamorphic rocks were originally igneous or sedimentary rocks that underwent changes from heat and pressure deep underground.
