Identify the differences between igneous, sedimentary, and metamorphic rocks, and learn how the rock cycle works Sedimentary rocks form through processes like erosion, deposition, and cementation, while igneous rocks form from the cooling of molten magma Learn some examples of each type of rock and how transformations take place.

Over time, the sediments can undergo compaction and cementation, forming a sedimentary rock
Sedimentary rock can change intometamorphic rock or into igneous rock.
The different layers (strata) of the rock tell a story of the history of the rock Geochemical analysis can pinpoint closely where the rock originated before being turned into a sedimentary rock. But the rock cycle displays the one rock is the raw material for another, because rocks go through three phases/types Igneous, sedimentary, and matamorphic rock.
To become a metamorphic rock it must be transformed by heat and pressure, which it can do directly (e.g Granite turning into gneiss) or after first turning into a sedimentary rock. A sedimentary rock can become an igneous rock through the process of melting and solidification If sedimentary rocks are subjected to high temperatures and pressures in the earth's crust or.
An extrusive igneous rock is formed outside a volcano
It cools slowly and has small/ not visible crystals So basically, if the sedimentary rock gets into a volcano, it can turn into an igneous rock. Loose sediments can become a sedimentary rock through the process of lithification These sediments are compacted due to intense pressure and then undergo cementation to form sedimentary rocks.
