What is a rock cycle?

By Ritesh|Updated : September 1st, 2022

A rock cycle occurs when the old rocks are continuously changed into new ones. Rocks can change throughout time and rarely do so in their original state. The molten lava cools and becomes igneous rock when it solidifies.

  • Small fragments of these igneous rocks are dispersed, transported, and deposited to create sedimentary rocks.
  • Metamorphic rocks are created when igneous and sedimentary rocks are heated and compressed.
  • Molten magma is created when metamorphic rocks still under intense heat and pressure melt. Once more, the molten lava can cool and crystallize as igneous rocks.
  • Rock has a cyclical nature that causes it to alter both the geologic cycle and, on planets with life, the biogeochemical cycle.

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.

Rocks may transform and not remain in their original form, and the Rock Cycle is where old rocks are transformed into new ones.
