TYPES OF ROCKS �Igneous �Sedimentary �Metamorphic

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 neverending process. Any rock can change into any other rock.
