Rocks are combinations of minerals that come in different colors and types, including igneous, sedimentary, and metamorphic. Igneous rocks form from cooling magma or lava, sedimentary rocks form from compression of sediments, and metamorphic rocks form from changes to existing rocks by heat, pressure, and chemical reactions. The rock cycle describes how rocks continuously change between these three types through geological processes.
