sedimentary rock. noun. rock formed from fragments of other rocks or the remains of plants or animals. uplift. noun. elevation of the Earth's surface due to tectonic or other natural activity. Metamorphic rocks start as one type of rock and—with pressure, heat, and time—gradually change into a new type of rock.

Rocks are cycled through various forms in what is called the rock cycle, a set of natural processes that form, break down, change, and re-form rocks over time. Temperature, pressure, and changes in environmental conditions at and beneath Earth's surface drive the rock cycle. As a result of the cycle, each type of rock can change into other types.
