The answer to the riddle “What turns polar bears white?” is “The cold.” Polar bears have a thick layer of fur that helps to keep them warm in the cold Arctic climate. Their fur is actually clear, but it appears white because it reflects the sunlight. Polar bears’ fur also helps to camouflage them in the snow and ice.
Polar bears are well-adapted to their cold environment. They have a thick layer of blubber that helps to keep them warm, and their paws are covered in fur to help them grip the ice. Polar bears are also excellent swimmers, and they can use their powerful claws to catch prey.
