Igneous rocks formed when liquid magma or lava magma that has emerged onto the surface of the earth cooled and hardened.
Is granite igneous or metamorphic or sedimentary.
The geological timescale and the processes that happen occur over a long period of time.
Even the granites that form via metamorphism of sediments are igneous because they pass through a melting stage.
The sedimentary rock becomes metamorphic with heat and pressure.
It erodes into sediment and then gets compressed into a sedimentary rock.

The granite melts into lava then cools becoming igneous.
Each kind of igneous rocks contains different minerals and has different structures.
All other types of rocks viz sedimentary and metamorphic originate from igneous rocks and therefore they are also called primary rocks.
Igneous rocks comprise about 95 of the total earth s crust.
The key difference between igneous rocks and metamorphic rocks is that igneous rocks are the oldest rocks on earth while metamorphic rocks are derivatives of igneous rocks and sedimentary rocks.
Igneous rocks are molten rocks expelled as lava that has cooled and become solid.
Granite is a light colored igneous rock with grains large enough to be visible with the unaided eye.
Igneous metamorphic and sedimentary the three main types of geological rocks are described.
Geologists study the geological properties of metamorphic rocks as their crystalline nature provides valuable information about the temperatures and pressures within the earth s crust.
Partial melt granitic type rocks are granitic gneiss which is a metamorphic rock.
Now compare it to the granite.
Igneous rocks sedimentary rocks and metamorphic rocks are the major three rock types in the earth s crust geologist made this classification based on the geological process that formed these rocks.
It forms from the slow crystallization of magma below earth s surface.
Granite type rocks granitoids are abo.
Sedimentary rocks are generally formed by matter that has settled beneath lakes and ocean floors.
Metamorphic rocks on the other hand are transformed rocks as a result of exposure to extreme heat and pressure beneath the earth s mantle.
The types of rock.
For the construction of housing roads tunnels canals etc.
Rocks found on the earth s surface come from inside the earth telling us a lot about the earth s interior.
Then due to various conditions within the earth the existing rock was changed into a.
A metamorphic rock on the other hand began as a rock either a sedimentary igneous or even a different sort of metamorphic rock.
