Question : Flat footed camels can walk easily in sandy deserts because:
Option 1: pressure on the sand is decreased by increasing the area of the surface in contact
Option 2: pressure on the sand is increased by increasing the area of surface in contact
Option 3: pressure on the sand is decreased by decreasing the area of the surface in contact
Option 4: pressure on the sand is increased by decreasing the area of the surface in contact
Correct Answer: pressure on the sand is decreased by increasing the area of the surface in contact
Solution : The correct option is pressure on the sand is decreased by increasing the area of the surface in contact.
Due to their large hooves, which increase the surface area in contact with the sand, flat-footed camels are well-suited for walking in sandy deserts. This adaption allows the camel's weight to be distributed more evenly, preventing it from sinking too deeply into the loose desert sand. The process at work here is similar to Bernoulli's principle in fluid dynamics, where uniform pressure distribution causes the camel's feet to "float" on the sand, decreasing movement effort and allowing them to travel effectively through sandy terrains. Flat-footed camels are very effective desert travellers due to their unique adaption that reduces the chance of becoming trapped in the sand and conserves energy.
