Question

Why can camels walk on top of sand but humans can not?

Answer 1

1)Due to natural adaptation the bottom surfaces of camels feet are broad. Hence the camels weight is exerted on a large area and the pressure on the sand is reduced. Therefore camels feet do not penetrate into sand and it become easy for them to walk.

2)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). ... If the weather is hot, the sand can feel very hot
