is it fragmentation
sand
Gravel and sand are broken rocks.
There isn't one specific chemical name for sand paper. It isn't just one chemical.
no.
Mixing sand and water is a physical change. When sand is combined with water, the individual particles of sand do not undergo any chemical transformation; they simply become wet and can be easily separated again. This process does not alter the chemical composition of either the sand or the water.
Chemical
Gas is not prepared from sand.
Chemical
Sand is primarily made up of silicon dioxide, which has the chemical formula SiO2. Glass is made by melting sand, so it also contains silicon dioxide at its core, hence the same chemical symbol for both.
Therew is only to types of weathering in my knowledge and they are Mechanical and Chemical (in scientific term). Mechanical is also know as physical.
Physical because you are not changing the substance.
The chemical equation for sand is SiO2, which represents silicon dioxide. Sand is primarily composed of silicon dioxide molecules arranged in a crystalline structure.
