TYPES OF ROCKS • Igneous • Sedimentary • Metamorphic
IGNEOUS ROCKS • Formed from molten material including volcanic lava, ash, or bombs as well as magma below Earth’s surface
TYPES OF IGNEOUS ROCKS BASALT GRANITE
SEDIMENTARY ROCKS • Made of layers that have been pressed or cemented together • Pebbles, sand, silt, or clay are sediments • Shells and bones can also be sediments
TYPES OF SEDIMENTARY ROCKS LIMESTONE SHALE COAL
METAMORPHIC ROCKS • Rocks that are changed by intense heat and pressure while inside Earth’s surface • Igneous, sedimentary, and even metamorphic rocks can be changed into different metamorphic rocks
