About this document
Types of Rocks for Grade 4 Students by linanovianti26 is a document available to read on EtoBox.
There are three main types of rocks: sedimentary, igneous, and metamorphic. Sedimentary rocks form from the compaction of materials like dirt, rocks, and shells over many years, and can sometimes show layers. Igneous rocks form from cooled magma and contain crystals. Metamorphic rocks form from other rocks undergoing heat and pressure. Rocks can go through a cycle where they are broken down and reform as different types of rocks over long periods of time.
