The vast majority of sand is the compound silica, or silicon dioxide, SiO2. But there will be all sorts of other things mixed up with the sand to give it its colour and so on.

Well, I am a chemist. Pure sand is made up SiO2. Although the sand that you likely see everyday is going to be made up many different compounds. Some sands may contain living organisms, some may contain Iron and trace amounts of other minerals and elements. So, the vast majority of the time, sand will be a mixture, unless it is pure, then it is a compound. Hope this helps.
Wee-Man.

A mixture is defined as a substance that is not pure, and mixed in with other things.
A compound is pure, and only contains one element.
So, sand is a mixture, because it is mixed in with lots of other things.

Sand from the sea is a mixture as it will contain, gains of dirt, mud, rock, dead animals, salt and other living things.
However pure sand, will be SiO2 and wherefore a compound.
