Answer:
Most beaches get their sand from rocks on land. Over time, rain, ice, wind, heat, cold, and even plants and animals break rock into smaller pieces. This weathering may begin with large boulders that break into smaller rocks. Water running through cracks erodes the rock.
The appropriate response is Oasis. It is shaped from underground streams or aquifers, for example, an artesian aquifer, where water can achieve the surface normally by weight or by man-made wells. Periodic brief rainstorms give underground water to manage common desert gardens, for example, the Tuat. Substrata of impermeable shake and stone can trap water and hold it in pockets, or on long blaming subsurface edges or volcanic barriers water can gather and permeate to the surface.
