What is the main component of sand?
Silicon dioxide, also known as silica, is an oxide of silicon with the chemical formula SiO2, most commonly found in nature as quartz and in various living organisms.
In many parts of the world, silica is the major constituent of sand. Silica is one of the most complex and most abundant families of materials, existing as a compound of several minerals and as a synthetic product. Notable examples include fused quartz, fumed silica, silica gel, and aerogels. It is used in structural materials, microelectronics (as an electrical insulator), and as components in the food and pharmaceutical industries.

I remember my teacher putting a small cubes of sodium in a container of water, once or twice.
The result was.... interesting. 😆😆

You are so right ! I'll do it the next time...!

Joris van Pelt,
Would have given your answer a thumbs up if you’d used Celsius or both!
There is a world beyond the USA!!!!!

Sand melts at the extremely high temperature of 3090 degrees F. When sand reaches its melting point it undergoes a complete transformation. Glass is then a form of liquid sand.
Different types of glass will slightly differ in their make up, but generally speaking, glass is a mixture of sand, other recycled glass, calcium carbonate, sodium carbonate,
and a whole lot of heat.

I thought sand was glass, but maybe, it is glass is sand. Could anyone explain further? Thank you, Christine, James's wife

Ron Harvey, quartz is made up from silicon dioxide.
