Rock Cycle

Three Types of Rocks Igneous… formed from magma(inside earth)/lava(outside earth) that has cooled and hardened

Three Types of Rocks Sedimentary… formed by sediments being cemented/pressed together

Three Types of Rocks Metamorphic… formed from rock that is changed by heat and pressure

What can happen to rocks??? Three things can happen to EACH type of rock Weathered/eroded and broken into fragments (sediments) then it will erode  cement/compress Undergo heat and pressure then it will change Melt then it will cool & crystalize
