The rock cycle is an illustration that is used to explain how the three rock types are related to each other and how Earth processes change a rock from one type to another through geologic time. Plate tectonic movement is responsible for the recycling of rock materials and is the driving force of the rock cycle...

THE INTERRELATIONSHIP AMONG THE ROCK TYPES IS REFERRED TO AS THE; ROCK CYCLE. ... If we examine the rock cycle in terms of plate tectonics, as depicted in the figure above, we see that igneous rocks form on the sea floor as spreading ridges. As the rocks cool, and more magma is introduced from below, the plate is forced...

The Rock Cycle ... The rock cycle goes round and round, taking hundreds of millions of years. Once the rock has been broken down into smaller bits it's got to somehow move. Streams and rivers carry the small bits towards the sea (continually wearing down as the they progress).

Minerals that make up rocks are constantly moved and acted upon by the environment. Environmental agents change one type of rock into an entirely new rock. The web of environmental processes that forms and changes rocks is known as the ROCK CYCLE.

Metamorphic Rocks: Formed from older "parent" rock (either igneous or sedimentary) under intense heat and/or pressure at considerable depths beneath the earth's surface. What is the Rock Cycle?; The rocks on Earth have been changed continually over time from one rock type to another.
