WEBJun 26, 2019 · A nonconformity is the old erosional surface on the underlying rock. Nonconformity in the Grand Canyon. Angular Unconformity. An angular unconformity is the contact that separates a younger, gently dipping rock unit from older underlying rocks that are tilted or deformed layered rock.
3.3: The Rock Cycle - Geosciences LibreTexts
WEBThe 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 - National Geographic Society
WEBDec 13, 2023 · The formation of clastic and organic rocks begins with the weathering, or breaking down, of the exposed rock into small fragments. Through the process of erosion, these fragments are removed from their source and transported by wind, water, ice, or biological activity to a new location.
The Rock Cycle - Education
WEBThe 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. For example, sedimentary rock shale becomes slate when heat and pressure are added.

WEBIgneous rocks are called intrusive when they cool and solidify beneath the surface. Intrusive rocks form plutons and so are also called plutonic. A pluton is an igneous intrusive rock body that has cooled in the crust. When magma cools within the Earth, the cooling proceeds slowly.
