Answer:
Stones and sand are solids whose particles are closely packed and held together by strong forces. Each grain can rest on top of another and support its weight, so they form a stable pile. Water is a liquid with particles that move freely past each other, so it cannot hold a shape and simply flows and spreads out instead of piling up.
