Sedimentary rocks are formed by sediment deposited in layers over time at the bottoms of lakes and oceans. Metamorphic rocks are changed by extreme heat and pressure over time. Igneous rock forms when magma cools and solidifies above or below the Earth's surface. The document discusses the formation of three main rock types and their everyday uses.
