The Rock Cycle Rocks and the Rock Cycle

Layers of the EARTH INNER CORE 800 miles thick and up to 13,000 F CRUST 5 to 25 miles thick and up to 1,600 F OUTER CORE 1,400 miles thick and up to 11,000 F MANTLE 1,800 miles thick and up to 8,000 F

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

TYPES OF METAMORPHIC ROCKS SLATE MARBLE

Describe the ROCK CYCLE and ways rocks can be changed: The series of continuous changes that rocks go through to create sedimentary, igneous, and metamorphic rocks. These changes are caused by heat & pressure, weathering/erosion, and cooling & melting
