It is first deposited by rivers. Then it is carried by waves form the ocean floor to the beach.
Some of it is carried up the shore and deposited higher up the beach. Some is deposited on the seabed.
Some beaches with black sand may be due to 'stamp sand', leftover material from copper ore crushing processes near bodies of water.
There are many reasons why, and I have really no clue, but i believe sand is important because of beaches. I love beaches! I'm only doing this because I got bored, so don't use this for science.

Sand dunes
When wind carrying sand slows down or is trapped by some obstacle, such as a boulder or plant, the sand gets deposited. As the sand accumulates, a sand dune can form. Dunes often form on beaches or in deserts. Sand dunes move over time as, little by little, sand grains get moved by the wind from one side of the dune to the other.
Beaches are formed by waves depositting sand.
Australian for sure, American beaches have little or no waves and the sand is very rough. Australian beaches are definetly the way to go, more waves finer sand and the atmosphere
