Rock Cycle - Transition to Igneous, Metamorphic, and Sedimentary Rocks
A fundamental idea in geology, the rock cycle illustrates how the three primary types of rocks—sedimentary, metamorphic, and igneous—change throughout geologic time. When a rock is pushed out of its equilibrium circumstances, it changes.
- For instance, an igneous rock like basalt may disintegrate and evaporate when exposed to air or melt when it is subducted beneath a continent.
- Rocks do not stay in equilibrium; instead, they change as they interact with new environments because of the driving forces of the rock cycle, plate tectonics, and the water cycle.
- The rock cycle illustrates how the three types of rocks are connected and how processes shift over time from one type to another.
What is a rock cycle?
Rocks may transform and not remain in their original form, and the Rock Cycle is where old rocks are transformed into new ones.
