In this case, sand is usually made from erosion by water. The ocean carries all kinds of materials through its currents these end up on our beaches in the form of sand that we walk on. The repeated exposure to turbulent currents, riptides, etc is what breaks down the rock fragments into what we know as sand.Web

The grains of sand that make up sand dunes on Earth and Mars have a hazardous existence because of the way that they travel.
