Rock Facts
Did you know that rocks are classified into three main types based on how they are formed? Igneous rocks form from cooled molten lava or magma, sedimentary rocks are created from compacted sediments, and metamorphic rocks develop from existing rocks transformed by heat and pressure. Each type of rock has unique characteristics and tells a story about Earth’s history. Rocks are found everywhere and are used in building materials, art, and even jewelry.
