Why is sand nonrenewable?

Answer 1

A nonrenewable resource is basically any resource that can be depleted. Sand, for use in making goods such as glass in concrete, is nonrenewable because once these products are made, the sand used cannot be cycled or brought back to its originally form, and sand is not continuously produced by the earth. Examples of renewable material resources are agricultural products, if sustainable farming techniques are practiced, because you can always continue gaining these products off of the land every year. Water can also be considered a renewable resource, but only if used carefully. This is because, ideally, you will use the water, but it will eventually evaporate, than precipitate, then replenish the water source that you originally used.
