Question

It is easier to walk in soft sand with flat shoe rather than sharp heels

Answer 1

The main reason it is difficult to walk on sand is because the sand grains are unconsolidated (loose). So with each step you take, you just move the sand grains around (similar to the plastic ball pits that children play in).

In contrast, if you walk on a hard sandstone, the grains are cemented and create a hard surface, so if you walk on solid rock, the grains mostly stay in place. You have a much more stable surface.

Answer 2

Answer:

Flat shoes have larger surface area hence the pressure applied on the sand is less but heels have smaller surface area hence pressure applied is more, it sinks
