This document discusses the three main types of rocks: sedimentary, metamorphic, and igneous. Sedimentary rocks form from sediment deposited over time in layers in bodies of water. Metamorphic rocks have been altered by extreme heat and pressure over time. Igneous rock forms when magma cools and solidifies, either above or below the Earth's surface.

2. Sedimentary rocks are formed by sediment that is
deposited over time, usually as layers at the bottom
