1 Answer

Answer :

(1) pressure on the sand is decreased by increasing the area of the surface in contact Explanation: Camels have broad, flat, leathery pads with two toes on each foot. When the camel places its foot on the ground the pads spread, preventing the foot from sinking into the sand. When walking, the camel moves both feet on one side of its body, then both feet on the other. This gait suggests the rolling motion of a boat, explaining the camel's 'ship of the desert' nickname. The pad supports the animal on loose sand in much the same way that a snowshoe helps a person walk on snow.
