How to Identify Rocks?


To identify rocks, you must first determine if your rock is igneous, sedimentary or metamorphic. Igneous rocks are tough, with a little texture or layering. They are mostly black, white and or gray and may look like lava. Sedimentary rocks are hardened sediment with layers of sandy stone. They are mostly brownish to gray in color and may have water or wind marks in them. Metamorphic rocks are tough rocks with layers of light and dark minerals. Once you have determined what kind of rock you have, check the rocks grain size and hardness. You can then look for rock charts that show what kind of rock you have.
