Granite is defined as a course grained rock that must have plagioclase feldspar, potassium (aka alkali) feldspar, and quartz. Granite can also have a number of secondary minerals like micas or hornblende, but these secondary minerals do not have to be present.
Yes. Granite and Rhyolite have the same composition.

The composition changes the appearance and colour of the granite. A granite that appears more red in colour will have more of the mineral orthoclase feldspar, whereas the lighter and more white in appearance will have less orthoclase and maybe more plagioclase feldspar and quartz in the composition.
Granite always contains the minerals quartz, feldspar (potassium feldspar or plagioclase feldspar), and mica (biotite or muscovite). These minerals give granite its characteristic appearance and properties.
No, the color of the granite does not affect its hardness. Granite is a dense and durable natural stone that is resistant to scratches and heat regardless of its color. The hardness of granite is determined by its mineral composition, not its color.

Yes. Granite and Rhyolite have the same composition.
Yes. Rhyolite and granite have the same composition. Rhyolite is the volcanic equivalent of granite.
The continental crust is similar in composition to granite. It is the outermost layer of the Earth's surface and is primarily composed of rocks like granite, which is rich in silica and aluminum.
Granite. Most of the crust is composed of granite. Feldspar is the most common mineral in the earth's crust.Silicon, (Si) and Alluminium, (Al).
The counterpart of Granite is Rhyolite,the counterpart of Gabbro is Basalt. Gabbro is mafic(Dark coloured) ,Granite is felsic (light coloured) Granite forms from magma of Granitic composition while Gabbro forms from magma of Basaltic composition.

Diorite is a rock that has a composition similar to granite, but with a different texture. Both rocks are composed mainly of quartz, feldspar, and mica minerals. Diorite is typically darker in color and has a coarser grain size compared to granite.
the mineral composition of granite isfeldspar,diamond,talc,chalk and other plutonic rocks
The composition of the continental crust is granitic overall, high in silicon and aluminum, when compared to the oceanic crust.
The composition changes the appearance and colour of the granite. A granite that appears more red in colour will have more of the mineral orthoclase feldspar, whereas the lighter and more white in appearance will have less orthoclase and maybe more plagioclase feldspar and quartz in the composition.
