The Rock Cycle. Many of Earth’s key processes function in cycles and rock cycle is no exception. The rock cycle is a web of processes that outlines how each of the three major rock types—igneous, metamorphic, and sedimentary—form and break down based on the different applications of heat and pressure over time.

The rock cycle describes the processes through which the three main rock types (igneous, metamorphic, and sedimentary) transform from one type into another. The formation, movement and transformation of rocks results from Earth’s internal heat, pressure from tectonic processes, and the effects of water, wind, gravity, and biological ...
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.
Apr 23, 2023 · The rock cycle is a natural process that describes how rocks are formed, broken down, and transformed into different types of rocks over time. It involves various geological processes such as weathering, erosion, deposition, compaction, cementation, melting, crystallization, and uplift. The rock cycle is a continuous process that occurs over ...
The rock cycle. 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 rock cycle is driven by energy from Earth's interior and the sun. Created by Khan Academy.

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 still active on Earth because ...
