Rock+cycle

**What is "Rock Cycle'?** The rocks don't stay the same forever, they are continually changing because of processes such as weathering and large earth movements. The rocks are gradually recycled over millions of years. This is called the rock cycle.

**How the different kinds of rocks are recycled?** Sedimentary rocks can be changed into metamorphic rocks because of high temperaturate and pressures. Metamorphic rocks can be changed into igneous rock because of melting. Igneous rocks can be changed into sedimentary rock becuase they erode then transported and deposited and then compaction and cementation presses the layers and sticks the particles together. This creates sedimentary rocks.
