What does sand turn into when under high pressure and high temperature?
it will turn into the metamorphic rock, Quartzite
How is quartzite obtained?
Quartzite is a metamorphic rock that forms when sandstone (which is composed largely of quartz) is subjected to high heat and pressure without undergoing melting. Since it is composed primarily of quartz, it shares the properties of quartz, such as high hardness.
What eventually happens to a grain of sand?
A quartz sand grain could combine with other rock particles to become sandstone which could then undergo metamorphism to become quartzite. Given enough time and weathering, it could simply become a part of a solution that reconstitutes elsewhere as part of a mineral crystal.
How does metamorphism change sandstone?
Sandstone can metamorphose into quartzite.
What type of metamorphic rock is formed by sand?
Sand forms sedimentary rocks such as sandstone. Sandstone containing mostly quartz can form the metamorphic rock quartzite.

What did quartzite used to be?
Quartzite used to be quartz sand, generally well sorted and quite pure. Quartz has a great propensity to crystallize, so sand grains will tend to bind together.

Why is quartzite very hard and more resistent than its parent rock?
Quartzite is a nonfoliated metamorphic rock that formed by the metamorphism of pure quartz sandstone. The intense heat and pressure of metamorphism causes the quartz grains to compact and become tightly intergrown with each other, resulting in very hard and dense quartzite.

Why is sand not as fast at melting ice as salt?
Sand isn't used for melting snow. Sand is used for traction.
What do you get by melting sand?
glass

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.
How hot does sand get?
Sand can get as hot as 3110 degrees Fahrenheit. When sand reaches that temperature, it is officially at its melting point.
What is the melting point of sand in Fahrenheit?
Sand is Silicon Dioxide or Silica. It's composition varies a bit, since "sand" isn't pure silica. That said, it melts at around 1650 degrees Centigrade +/- 75 degrees or so for impurities. Roughly 3000 degrees F.
