Is sand a nonrenewable resource

Answer 1

In the same sense that Oil is a non renewable resource, sand is a non renewable resource as well. There is an awful lot of sand on the Earth to last for centuries, perhaps millenia, however if it was used as much as oil for example, it would eventually run out. This is so because rocks take a long time to reach a 'sand state' in sufficient quantities to be considered a resource so eventually, IF the sand did run out, people would have to wait at least several centuries before there would be enough sand again to be used. There is no renewing in this resource at all, the rock cycle is a closed system, however there are NOT equal quanities of material at each stage of the cycle, therefore making it unrenewable.

Answer 2

Because the earth creates rocks and the rocks break and turn into sand... so there you have it
