The rock cycle
The rock cycle is the cycle of how rocks are formed and changed into different types of rocks. There are 3 main types of rocks;
Igneous: Igneous rocks are formed by magma. the magma rises to the surface and when it is cooled it becomes an igneous rock. igneous rocks can both be formed above ground or underground where the magma cools very slowly.
Sedimentary: Sedimentary rocks are rocks that are formed with sediments from other rocks that have been broken down from wind and rain. they are formed. the sediments can be carried and get stuck together to form layers and then eventual get stuck together to form a sedimentary rock.
Metamorphic: if a sedimentary rock is heated it it becomes a metamorphic rock. the sedimentary rock gets pushed slightly underground and then gets heated and the sedimentary rock sticks together more and becomes a metamorphic rock.
That's not just the cycle though, there's more. if enough heat and pressure is applies an igneous rock can become a metamorphic rock, metamorphic rocks and sedimentary rocks, with enough weathering and erosion, can become sediments, and igneous rocks can be melted down back into magma.
