- The rock cycle is a concept of geology that describes the transition of rocks between the three rock types: igneous, sedimentary, and metamorphic. The cycle outlines how each rock type can be converted to another rock type through geologic processes.

Apr 24, 2024 · The Rock Cycle describes how the three main rock types that compose the Earth’s lithosphere are constantly transformed into one another through geologic processes. These three rock types are those we learned about in the previous chapter: igneous, sedimentary, and metamorphic rocks.
The rock cycle describes how the three main rock types—igneous, sedimentary, and metamorphic—change from one type to another. These changes occur through processes such as melting, solidification, and lithification.

The three main rock types are igneous, sedimentary, and metamorphic. Crystallization, erosion and sedimentation, and metamorphism transform one rock type into another or change sediments into rock. The rock cycle describes the transformations of one type of rock to another.
Dec 13, 2023 · The Rock Cycle. Use this printable infographic to learn about the rock cycle. There are three main types of rocks: sedimentary, igneous, and metamorphic. Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming —that are part of the rock cycle.
Apr 11, 2024 · The rock cycle is driven by two forces: (1) Earth’s internal heat engine, which moves material around in the core and the mantle and leads to slow but significant changes within the crust, and (2) the Sun which powers the hydrological cycle, moving water, wind and air along Earth’s surface.
The rock cycle is the set of processes by which Earth materials change from one form to another over time. The concept of uniformitarianism, which says that the same Earth processes at work today have occurred throughout geologic time, helped develop the idea of the rock cycle in the 1700s.
