Polar Bears And Penguin Research Paper

Polar bears and penguins are usually found mostly in the arctic or cold areas of the earth. Sometimes it can get to as cold as - 29℃, with little protection the weather can be deadly. Polar bears and penguins have so many different adaptations and ways of protecting themselves from the weather and keeping warm by using convection, conduction and radiation. Some ways they keep warm by using the 3 heat loss methods are . . .

Polar bears lose a lot of heat just through their tail and ears. Their tails and ears have actually adapted to their cold conditions, for example in the desert the foxes have larger ears and larger tails so they can lose heat faster. So in the arctic you will find that most of the animals have smaller ears and tails so not much heat can escape. This is a form of radiation because …show more content…
Polar bears they have a thick layer of blubber that can be up to 10 cm thick covered with another 15 cm of fur, and penguins to have a thick layer of blubber several centimeters thick. This is a very good way for the penguins and polar bears to keep warm. Blubber is conduction because it is insulating the animal, and the animal touches cold air.

The polar bear is a big animal so it absorbs more heat than a smaller animal (like the penguin) so the penguins huddle - since they are so small it’s hard for them to prevent heat loss. They actually huddle together in large groups to make one big “Penguin”. The penguins radiate heat from one to another which makes a huge outer layer of heat. Although for the penguins on the outside of the huddle they are heat convection because warm air is coming out of the penguin and cold air is coming back into the penguin.

Polar bears and penguins adaptations are pretty similar because they both live in the arctic and they need similar things to survive. Conduction, convection and radiation are all big parts of keeping polar bears and penguins
