Question

When we stand on loose sand our feet goes deep into the sand but when we lie down we do not go deep into the sand.why?

Answer 1

Because in standing position the pressure of our feet becomes larger but in case if we lie then pressure is distributed to a large surface area and hence there is low pressure on Sand and we don't go deep.

Answer 2

Answer:

when we stand on loose sand surface area decreases as pressure increases and feet sinks .when we lie on loose sand surface area increases and our body sinks in very little .

pressure is inversely proportional to surface area
