网页2020年11月2日 · The rock cycle is the process that describes the gradual transformation between the three main types of rocks: sedimentary, metamorphic, and igneous. It is occurring continuously in nature through geologic time.
Rock cycle - Understanding Global Change
网页What is the rock cycle? Rocks can be: (1) made of minerals, each of which has a specific crystal structure and chemical composition; (2) made of pieces of other rocks; (3) glassy (like obsidian); or, (4) contain material made by living organisms (for example coal, which contains carbon from plants).
The Rock Cycle - National Geographic Society
网页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.

网页2024年9月11日 · What is a rock cycle? The rock cycle is a process that explains the basic relationships among igneous, metamorphic, and sedimentary rocks. The process depends on temperature, pressure, time, and changes in environmental conditions in the Earth’s crust and at its surface.
Rock cycle - Wikipedia
网页The rock cycle is a basic concept in geology that describes transitions through geologic time among the three main rock types: sedimentary, metamorphic, and igneous. Each rock type is altered when it is forced out of its equilibrium conditions.
5.1: The Rock Cycle - Geosciences LibreTexts
网页2024年4月11日 · 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.
4.6: The Rock Cycle - Geosciences LibreTexts
网页Rocks at the surface are lying in place before they are next exposed to a process that will change them. Several processes can turn one type of rock into another type of rock. The key processes of the rock cycle are crystallization, erosion and sedimentation, and metamorphism.
