Granite rock formed
WebIn this study, direct shear tests of intact granite under various TM coupling conditions were conducted, followed by 3D laser scanning tests of shear-formed fractures. Test results demonstrated that the peak shear strength of intact granite is positively correlated with the normal stress, whereas it is negatively correlated with the temperature. http://www.actforlibraries.org/how-granite-is-formed/

WebGranite is an igneous rock and as such is formed when molten rock, magma, cools slowly. Magma is found between the mantle and the crust of the earth, and often flows towards the surface of the earth. As the magma rises to the surface though it starts to cool down, and unless it finds an escape route, could solidify as an intrusive rock formation. http://www.actforlibraries.org/how-granite-is-formed/#:~:text=Granite%20is%20an%20igneous%20rock%20and%20as%20such,route%2C%20could%20solidify%20as%20an%20intrusive%20rock%20formation.
