Weathering causes the granite to break down into small particles - sand. The sand becomes buried and compacts into sandstone. If the sandstone continues to be buried and comes into close contact with high heat, such as magma, it can be turned into quartzite.
Metamorphic. Original form: sandstone (sedimentary).
Quartzite--sandstone. Marble--limestone. Slate--shale. Gneiss--basalt or granite.
Metamorphosed sandstone may become quartzite and limestone may become marble.
Exposed granite will weather and erode. The final product of the weathering and erosion of granite are deposits of silica sand. The sand may be deposited by the wind (in dunes), or in shallow marine environments. As these deposits are added to over time, they are compacted and cemented, forming sandstone. Under conditions of intense heat and pressure from depth of burial, or from pressures from tectonic plate collisions, the individual quartz sand grains in the sandstone can recrystallize to form larger interlocking crystalline structures. This is known as metamorphosis, and the new rock that is formed from the sandstone is quartzite, a metamorphic rock.
The Granite
It doesn't. Granite is an igneous rock, not metamorphic. However, quartzite is metamorphic and is made from sandstone.
Quartzite, granite, and sandstone are all types of sedimentary or metamorphic rocks. They are related in the sense that they are formed from different processes involving the compression and transformation of sediments. Quartzite is derived from sandstone through intense heat and pressure, while granite is an igneous rock that forms from the cooling and solidification of molten magma. Sandstone, on the other hand, is formed from sand particles that are compacted and cemented together over time.
The forces of the mountain building slowly pushed the granite upward. This formed a mountain. Water and wind slowly wore the granite away. The sand remaining was carried by streams to the ocean. Over millions of years layers of sediment piled up on the ocean floor and changed to sandstone. Sandstone is a Sedimentary rock. Over time, the sandstone became deeply buried. Heat and pressure changed the sandstone to quartzite, a metamorphic rock. I got this from my science homework. :)
Granite must be exposed on the surface for a long time, giving enough time for weathering. The sediments then, could have transported to a basin nearby and consolidated. In geology SAND is referred to grain size in the limits of a geometric scale between 2-1/16 mm. When sediments of the mentioned size are consolidated, it gives rise to SANDSTONE. Some time later, due to tectonic activity (or due to piling up of sediments) the sandstone bed undergone metamorphism (i hope u understand the processes involved) and metamorphosed sandstone is quartzite.
The minerals in sandstone recrystallize when granite first turns into sandstone a gritty sedimentary rock under weathering and erosion and then into the metamorphic rock quartzite under heat and pressure and then it goes all the way throughout the rock cycle and back into its original form of granite a igneous rock and is formed when magma recrystallizes.

Quartzite--sandstone. Marble--limestone. Slate--shale. Gneiss--basalt or granite.
The Granite mountain becomes weathered and eroded by surface processes and the debris is carried off and separated into its sandy components by water flowing in rivers. The sandy sediments pile up and become buried by more sediments and as this happens they fuse together to form a new sandstone rock. Should this new rock become involved in a continental collision that heats up and squashes the sandstone rock this will metamorphose into a quartzite.

Granite becomes Sandstone when water erodes the Granite on Earths surface, and then deposits the sediment.
