What is the most direct cycle of relationships between the three major rock types?

(igneous, sedimentary, and metamorphic rocks)


What are the ways that rocks change and what are their results?What is the most direct cycle of relationships between the three major rock types?
Igneous rocks are formed directly from magma that has cooled. Diamonds originate from igneous rock known as Kimberlite. Size of the mineral grains is determined by the rate of magma's cooling. Large grained rocks (e.g. granite) cooled slow whereas fine grained (or no visible graining) such as a basalt, cooled rapidly.





Metamorphic rock is either igneous or sedimentary rock with an altered crystalline structure or chemical structure due to changes in pressure and/or temperature normally at depth but without reassimilation into magma.





Sedimentary rocks are made of grains weathered out of igneous, metamorphic, and/or other sedimentary rocks. Material is transported, and re-deposited elsewhere in layers. Many years pass and subsequent layers compress older underlying layers, squeezing the pore water out. With enough time and confining pressure...voila...sedimentary rock.What is the most direct cycle of relationships between the three major rock types?
They all do relate


Igneous, anything that is a result of lava extruded from the earth, anything that melts into the mantle of the earth and comes back up later.


Sedimentary is any rock that forms as sediment sand calcium build up etc. they form a solid, so anything that settles and forms a solid.





Metamorphic one or more of the previous rocks that are changed into different rocks because of heat or pressure. Rocks that look like a bunch of rocks together or diamonds





But any one of these rocks can become the other under the rt. conditions.


Hope this helps
