Chemical weathering of granite typically involves the breakdown of minerals like feldspar and mica due to reactions with water and acids. This process can result in the formation of clay minerals, altered feldspars, and dissolved ions that are carried away in solution. Over time, this weathering can lead to the decomposition and eventual disintegration of the granite rock into smaller fragments.

When component minerals are combined in a rock mixture, they are physically and chemically bonded together to form the rock. Their individual characteristics can still be observed under a microscope, but they lose their individual identity within the rock.
When a metamorphic rock is weathered, it undergoes physical and chemical breakdown due to exposure to the elements. This can lead to the rock breaking apart into smaller pieces or being chemically altered, potentially forming new minerals. Over time, the weathering process can transform the metamorphic rock into sediment that may eventually become part of a sedimentary rock.
I reiley don't know.

It gets weathered into sediment or it could be subjected to heat and pressure and become a metamorphic rock, or it could melt into magma and cool into an igneous rock.
With the extreme heat and pressure causing the metamorphism into gneiss, the constituent minerals recrystallize into bands, usually alternating from light colored to dark, perpendicular to the direction of the pressure which is being applied. The exact cause of the banding is not fully understood at this time.
When granite is subjected to high heat and pressure, it undergoes metamorphism and can transform into a metamorphic rock called gneiss. This process involves recrystallization of minerals within the granite, resulting in a new texture and mineral composition.
it turns to sediment
Plagioclase feldspar weathers into clay minerals, such as kaolinite, through a process known as hydrolysis. This chemical weathering process breaks down the feldspar structure, releasing ions that combine with water and oxygen to form the new clay minerals.
When granite is subjected to heat and pressure, it undergoes a process called metamorphism and can transform into a metamorphic rock called gneiss. The mineral composition and texture of the granite change during this process, resulting in a foliated texture and alignment of minerals in the gneiss.

When sedimentary rocks are weathered and eroded, they turn into sediments. And after compaction and cementation of the sediments, it will turn back into sedimentary rock.
