The five main types of rocks are sedimentary, igneous, metamorphic, carbonate, and organic. Sedimentary rocks are made up of particles that have been deposited by water or wind over time. Igneous rocks are formed when molten material solidifies quickly, usually in volcanic eruptions. Metamorphic rocks are changed from one type to another due to high pressure and temperature. Carbonate rocks are formed through the process of precipitation, where carbon dioxide is dissolved in water and then deposited as a mineral. Organic rocks are composed of organic compounds such as cellulose, which makes up plant cell walls.
