Magma starts the rock cycle. Magma is a complex high-temperature fluid substance. Temperatures of most magmas are in the range of 1300 °F to 2400 °F. Magma is soon cooled and crystallized into igneous rocks.

Igneous Rocks

Igneous Rocks are formed when magma is crystallized and hardened. Igneous rocks can melt back into magma, or be changed into sedimentary or metamorphic rocks.

Sedimentary Rocks

Sedimentary rock is formed by sediments being compacted and cemented. Sedimentary rocks can be turned back into sediments by going through the process of weathering, erosion, and deposition.

Metamorphic Rocks

Metamorphic rocks are the oldest rocks. They are formed two ways. The first way is sedimentary rocks being heated and put under pressure. The second way is Igneous rocks being heated and put under pressure. Metamorphic rocks can be melted into magma. Then the rock cycle starts over again.
