noun
- 1. an idealized cycle of processes undergone by rocks in the earth's crust, involving igneous intrusion, uplift, erosion, transportation, deposition as sedimentary rock, metamorphism, remelting, and further igneous intrusion.

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.
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.

- How long does it take for a rock to be in a different form?The short answer is that the rock cycle takes millions of years. Keep reading for more detail. Creating metamorphic rocks takes millions of years b...
- Do Rocks take affect by season??No, you must remember, we are talking about thousands of miles beneath the Earth's crust. The seasons have no effect on the magma beneath the Earth.
- what do you mean by the lava and magma lamp?A lava lamp is a somewhat popular decoration. It’s basically a tube full of wax and/or other materials with a heat source at the bottom. The video...

- Isn't deposition when a gas directly turns into a solid?Sorry if I'm late, but deposition actually means both the process of turning a gas into a solid and the definition listed in the video. Good job on...
- Can all types of soil,dirt, and sand turn into rock?Yes. Soil, sand, and dirt can all lithify into rock. Soils that have turned into rock are called paleosols and aren't very common but I've seen them.
In the rock cycle the three main rock types are igneous, sedimentary, and metamorphic. Arrows connecting the three rock types show the processes that change one rock type into another. The cycle has no beginning and no end. Rocks deep within the Earth are right now becoming other types of rocks.
Aug 11, 2022 · 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 hydrological cycle, which is the movement of water, ice, and air at the surface, and is powered by the sun.
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.
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.
