Are you ready to make some noise? It"s International Rock Day! Wait, not that sort of rock. On this day, we"re all about granite, limestone and slate. There are three types of rock: igneous are formed from solidified magma and lava; sedimentary rocks are layers of sedimentary particles such as sand; and metamorphic rocks are the result of heat and pressure on other kinds of rock.
