Playas (spelled 'Players' in this question, likely a typo) are shallow, flat-floored desert basins that periodically fill with water. They are formed by the deflating action of winds, which remove fine particles and leave behind a depressed, flat surface. This is distinct from glacial, river, or marine erosion processes. Playa formation is characteristic of arid and semi-arid regions where wind is the dominant erosional agent.
