Igneous Sedimentary Metamorphic TYPES OF ROCKS
IGNEOUS ROCKS • Formed from molten material such as magma • Occurs below or at the Earth’s surface
TYPES OF IGNEOUS ROCKS PUMICE SCORIA ANDESITE
SEDIMENTARY ROCKS • Rocks are exposed to erosion and break down into sediments • Pebbles, sand, silt, or clay are sediments • Shells and bones can also be sediments • Layers of sediments are pressed or cemented together to create sedimentary rocks
TYPES OF SEDIMENTARY ROCKS CONGLOMERATE BRECCIA SANDSTONE
METAMORPHIC ROCKS • Rocks that are changed by intense heat and pressure • Physical and/or chemical change • Igneous, sedimentary, and even metamorphic rocks can be changed into different metamorphic rocks
TYPES OF METAMORPHIC ROCKS GNEISS PHYLLITE SLATE
ROCK CYCLE • The rock cycle is a never-ending process. • Any rock can change into any other rock.
