The rock cycle is the continuous process in which new rock forms from old rock. Rock has been an important natural resource as long as humans have existed. Also, rock is a naturally occurring solid made from one or more minerals and organic matter. Each type of rock on the rock cycle can either change into metamorphic, sedimentary, or igneous rock. Rocks can follow various paths in the rock cycle. The location of the rock determines which forces will impact it the most. Rocks can change in many different ways and it doesn't always have to be the same way every time. Rocks are affected differently if they are inside the Earth than they are when they are at the surface. Overall, the rock cycle is a continuous process that transforms rocks.
