Rocks are all around us! They make up mountains, beaches, and even the ground beneath our feet. Rocks are made of minerals, and there are three main types: igneous, sedimentary, and metamorphic. Each type is formed in a different way. Igneous rocks come from cooled lava or magma. Sedimentary rocks are made from layers of sediment pressed together. Metamorphic rocks are formed when other rocks are changed by heat and pressure.
This worksheet will help you learn some important vocabulary, test your knowledge, and think critically about rocks!
