The two rock types have the same chemistry.
Why does granite form the way it does.
Freeze thaw and chemical weathering wear down the areas of rock that have a large amount of joints faster than those that don t have cracks for water to enter.
They heat up their surroundings through radioactive decay.
Granite is formed by the solidification of magma under the earth s surface.
Granite is actually made up of several different minerals including feldspar and quartz.
Granite often has joints that are not evenly spread.
Continents are hot because they are where the majority of our planet s uranium and potassium exist.
These tors have been formed by a combination of freeze thaw weathering and hydrolysis a form of chemical weathering.
Quartz feldspar and mica.
Granite forms when the continental rocks melt a process that occurs from high heat and the addition of volatiles water and or carbon dioxide.
The main processes that affect it are freeze thaw and hydrolysis.
Granite is an intrusive igneous rock which means it was formed in place during the cooling of molten rock.
To form granite magma must first cool underground.
Granite is composed mainly of quartz and feldspar with minor amounts of mica amphiboles and other minerals.
Molten rock or magma that would have formed granite had it stayed in the earth s crust but instead managed to erupt onto the surface of the earth forms a rock called rhyolite.
It is an intrusive igneous rock.
Granite is formed within the crust of the earth when felsic magma that is magma that is rich in silica cools down without reaching the surface.
Generally the slower the molten rock cooled the larger it s mineral crystals with k feldspar megacrysts forming in special circumstances greater than 5cm.
Since the time required to form granite is rather long it is both a strong and valuable stone.
Granite is formed from the slow cooling of high silicate magma intrusions that have risen through the crust and formed large bulbous chambers of molten material called plutons.
Granite forms from the slow crystallization of magma below earth s surface.
Because it remains beneath the surface as it is cooling it forms large crystals ie you can see the individual crystals without need of a microscope or hand lens.
The crystals of granite form while the molten material inside the earth s crust cools relatively slowly.
Granite is made up of three minerals.
In short your granite kitchen countertops were molten lava at one point.
It is composed mainly of natural quartz and feldspar with subtle amounts of mica amphiboles and other organic minerals.
This is an extremely slow process.
