Multiple choice

Flat footed camels can walk easily in sandy deserts because

  1. pressure on the sand is decreased by increasing the area of the surface in contact

  2. pressure on the sand is increased by increasing the area of the surface in contact

  3. pressure on the sand is decreased by decreasing the area of the surface in contact

  4. pressure on the sand is increased by decreasing the area of the surface in contact

A Correct answer
Explanation

Pressure = Force / Area. Flat feet increase the surface area in contact with sand. For the camel's weight (constant force), larger area means LESS pressure on each unit of sand. This prevents sinking, similar to how snowshoes work on snow.
