Aug 22, 2023 · The rock cycle is an ongoing process that converts one type of rock into another. The rock cycle is the natural, continuous process that forms, breaks down, and reforms rock through geological, chemical, and physical processes. Through the cycle, rocks convert between igneous, metamorphic, and sedimentary forms.
Sep 2, 2019 · Rocks are broadly classified into three groups: igneous, sedimentary and metamorphic, and the simplest diagram of the "rock cycle" puts these three groups in a circle with arrows pointing from "igneous" to "sedimentary," from "sedimentary" to "metamorphic," and from "metamorphic" to "igneous" again.

Diagram of the rock cycle. Legend: 1 = magma; 2 = crystallization (freezing of rock); 3 = igneous rocks; 4 = erosion; 5 = sedimentation; 6 = sediments & sedimentary rocks; 7 = tectonic burial and metamorphism; 8 = metamorphic rocks; 9 = melting. The rock cycle and plate tectonics [1]
Apr 23, 2023 · Modified date: 23/04/2023. 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.
A simplified diagram of the rock cycle highlighting some of the UGC concepts related to this process. Molten lava cooling to form igneous rocks forming in Hawai’i National Park (left) metamorphic rocks in Death Valley National Park (right). Source: NPS Igneous Rocks and NPS Metamorphic Rocks.
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.
Dec 13, 2023 · 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. Sedimentary Rocks. Sedimentary rocks are formed from pieces of other existing rock or organic material.
