A mixture.
mix the salt and sand into a glass of water. The sand would settle at the bottom of the glass, and the salt would dissolve into the water. pour off the salt water, wait for the water to evaporate, and you will be left with salt, and sand.
Sand grains will not dissolve in water. Therefore, sand and water can not form a solution. Salt and water can make a (saline) solution, because the salt crystals will dissolve completely into the water.
Yes sand can turn into glass
No, sand and water mixed together don't make a solution
The Journey into the hole
glass feels smooth and glass is made from sand and water =]
Yes, glass is made by melting glass and then blowing it into a bubble with a long tube. After the bubble dries. It is glass.
sand makes glass and glass make sand its a reverse psychology :)

Water and sand.

sand is crushed up rocks into fine grains but the specific thing that makes glass is the Silicon Dioxide
Both glass and concrete contain sand. Sand is melted to make glass. It is mixed with aggregate (gravel) portland cement and water to make concrete.
sand(silica), water (H2O)
Sand, or silicon oxide, is fairly inert. It does not dissolve in water. Sand is mostly the same material as glass. So it does not dissolve any faster than glass dissolves in cold water. Hydrofluoric acid is, however, another matter.
Common glass is made from sand, SiO2, Na2O and CaO. Concrete is a mixture of rocks (aggregate), sand, and water.
