in such a cold place.

it is very thick. This thick fur keeps the bear warm on the land and stops it getting wet when it is swimming.
(2) ……………………………… This means that the bear appears to be white like the snow and ice around it.

extra warmth.

protects the bears from the cold. (3) ……………………………… Polar bears hunt seals for food and these
are difficult to find in the summer when the ice melts.
