Question

What is the most likely reason that polar bears are found in the Arctic but not in Antarctica? Antarctica does not provide a suitable habitat for polar bears. Polar bears, which were derived from brown bears that lived in the Northern Hemisphere, are unable to travel long distances. Polar bears, which were derived from brown bears that lived in the Northern Hemisphere, can migrate long distances, but they are either unable or unwilling to travel across tropical areas that lie between the Arctic and Antarctica. Continental drift prevented the polar bears from going to Antarctica.

Explanation / Answer

Ans is option C

Polar bears are found in arctic i.e north poleand antarctica is on south.

Though polar bears derived from brown bears but when continental drift happened and both the poles seperated out the polar bears got trapped there.

Now when they had to survive there they hunted seals in ice and got adapted.

Now though they can travel to antarctica but they are unable to as they cannot travel through tropical areas lying in between whose temperature conditions are quite high
