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.
What two factors in the rock cycle may change sandstone to quartzite?
Heat and pressure
Describe how the granite of a mountain could change first into sandstone and then into quartize?
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.
What geologic process change granite igneous rock into gneiss metamorphic rock?
Heat and pressure cause granite to change to gneiss.
When limestone is heated it become sandstone?
No, limestone is a carbonate rock formed through chemical precipitation. Sandstone is a classification used for sedimentary rocks ranging in various sizes and compositions. Limestone is CaCO3 where as sandstones are usually quartz (SiO2) and feldspars.

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. :)
How do the growth of grains in sandstone change to 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.
What happens to the minerals in sandstone when it changes into quartzite?
The minerals in the sandstones usually recrystallize when it changes into quartzite. Heat must be applied to sandstone to change it into quartzite.
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.
How do you describe how the granite of a mountain could change first into sandstone and then to quartzite?
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.
What does sandstone change to?
That depends on what happens to it. If it is sufficiently heated and compressed it will metamorphose to quartzite.
How does metamorphism change sandstone?
Sandstone can metamorphose into quartzite.

Nobody knows and that is sad sorry if you wanted the answer that is kind of funny I am not giving the answer but this website is for answers
