sand pile
Gritty play heap
A sand pile is an accumulation of sand heaped in one place, whether naturally formed by wind or water or deliberately created for construction, play, or storage.
Children play in sand piles; contractors keep them on job sites.
In physics, sand piles serve as models for studying how granular materials behave under stress.
