Rocks and How They Form

There are three different kinds of rocks: Igneous, Sedimentary,and Metamorphic. Each Rock is formed differently. Igneous rocks form from melting and resolidifying. Sedimentary rocks and formed when sediments and cemented and compacted together. Metamorphic rocks are formed when either igneous or sedimentary rocks are put under heat and extreme pressure.

The Rock Cycle

The Rock Cycle is just the cycle rocks go through to become other or the same rocks. Any rock can become any rock over again. It can melt and become an igneous rock, or it can be subdued to heat and pressure, or it can be weathered and eroded, then cemented and compacted into a sedimentary rock
