First of all, the granite erodes. This means the original rock breaks down due to weathering. Wind, water, ice, they can all do that. As the rock breaks down into smaller and smaller parts, it eventually turns into sand. The sand is then deposited somewhere (let's say a beach), and then buried under more sand.
As more and more layers of sand get on top of the original sand, there is more pressure, and eventually, the pressure becomes big enough to turn the sand into sandstone.
But the process of sedimentation doesn't stop, and after enough time, there is enough pressure to deform the sandstone. This is where metamorphism enters the stage. As more and more pressure is added, the volume of the sandstone decreases. Now, there are different ways in which the volume of something can be decreased. That is removing the empty space, and putting the atoms in a crystalline texture. As the sand originally comes from granite - which is a very silica rich rock - there will be a lot of silica in the sandstone. The crystal that forms then, will be largely silica. Pure quartz is 100% silica. So if the sandstone that we have starts to form crystals to decrease it's volume under pressure, we get the quartzite.

Describe how the granite of a mountain could change first into sandstone and then into quartzite?
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.
A layer of sandstone is in contact with a mass of granite The granite contains small pieces of the sandstone Which rock is older?
The Granite
If a mass of granite is in contact with a layer of sandstone that contains small pieces of the granite which rock is older?
granite
Is granite or sandstone more expensive?
Granite is more expensive as it is made under the earth (metamorphic rock) and harder to extract than sandstone which is a sedimentary rock
What is the odd one out of granite basalt sandstone?
Sandstone is the odd one out as it is a sedimentary rock, as opposed to granite and basalt which are respectively felsic and mafic igneous rocks.
How can the granite of a mountain change first into sandstone and then into quartize?
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.

How does change granite into sandstone?
Granite becomes Sandstone when water erodes the Granite on Earths surface, and then deposits the sediment.

Is sandstone a scoria granite or pumice?
None of those. Scoria, Pumice and Granite are igneous rocks. Sandstone is sedimentary.
Is the great wall of China made of granite or sandstone?
granite
How does the granite of a mountain change first into a sandstone into a quartzite?
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. :)
