There are two main sources:

  1. Dead aquatic organisms (such as shells, fish bones etc.) matter grind together and get broken down into tiny little grains which are washed onto shores,forming large deposits.
  2. The result of the erosion of the lithosfere (rocks) oven hundered of millions of years of sea tides, rain (very often acid rain in the past geologic eras), wind erosion and thermic amplitudes.

Sand existed in all Fanerozoic eon, and possibly was first created in the Proterozoic eon.
