Rock Cycle Diagram
By: Abby Watts
Rock Examples and Forming
Sedimentary rocks are formed when sediment is deposited out of air, ice, wind, gravity, or water flows carrying the particles of suspension.
Metamorphic rocks are formed by the physical or chemical alteration of heat and pressure of an existing igneous or sedimentary material into a denser form.
Igneous rocks are formed through the cooling and solidification of magma or lava. They may form with or without crystallization either below the surface (plutonic) or above the surface (volcanic).
How The Rock Cycle Works
In more detail, the rock cycle doesn't really have a beginning. It can start with any rock which can change into either of the other rocks. Some of the things that can change a rock into another are, weathering, erosion, deposition, and heat & pressure. All of those things can different change a certain rock into another one. When heat is applied to a rock or mineral, it turns into magma that melts into another rock after it cools down. Another way is when a bunch of different materials turn into a rock by compacting and then the sediment gets cemented together. Sedimentary rocks, metamorphic rocks, and igneous rocks all form in different ways like I said above.
