LIFE AT THE NORTH AND SOUTH POLES

Activity:

Talking about life in the Polar Regions

[LO 1.2]

ANIMAL LIFE AT THE NORTH POLE (The Arctic)

Figure 1
Figure 1 (graphics1.png)

Wolves, bears, squirrels and small birds live in the forests and in the summer the caribou, which is a sort of American reindeer, migrates to the north where it lives off wild plants.

Musk oxen live off the tundra throughout the year. They defend themselves from attacking wolves by standing in a tight circle.

In the winter most of the animals hibernate. Bears sleep in their lairs for most of the time and the squirrels curl up in their snug holes. They eat sufficient amounts of food in the summer to provide their bodies with energy through the winter.

Figure 2
Figure 2 (graphics2.png)

Walruses also live here. They are family of the seals. They are mammals that are born live and drink from their mothers.

Figure 3
Figure 3 (graphics3.png)

Polar bears are among the largest animals in the world. They have a thick, soft layer of hair against the skin and longer hair that forms a layer of fur over it.

Animal life at the South Pole (Antarctica):

Figure 5
Figure 5 (graphics5.png)

The albatross is one of the largest of all the seabirds, and also lives at the South Pole. These birds fly over the sea looking for food in the water.

The largest animal in the world, the blue whale, lives in the waters of Antarctica. It grows to a length of 30 metres.

Very few types of animals live in Antarctica, but in the summer months seals and penguins go there to breed. The young are safe because there are relatively few predators to catch them.

Figure 6
Figure 6 (graphics6.png)

Many different kinds of penguins live at the South Pole. The largest is the emperor penguin that can grow up to one metre in height. These birds cannot fly but they do swim very well.

How do people survive at the poles?

Figure 7
Figure 7 (graphics7.png)

The Inuit people live in the Arctic region. They keep warm by wearing clothes made of animal skins. They live in small villages where it is necessary to melt ice to obtain water in winter.

Figure 8
Figure 8 (graphics8.png)

They hunt to obtain food and live in ice huts called igloos. They build circles of ice blocks on top of each other, making the circles smaller and smaller until they form a dome. The spaces in between the blocks are filled with snow.

Another group of people, the Saami, lives in Lapland. They are well known for keeping reindeer for milk, meat and fur. They enjoy wearing traditional clothes when taking tourists for rides on snow sleds.

But these people work in factories nowadays and live in houses made from stone and wood. They wear modern clothes and ride around on snowmobiles.

Write a paragraph of 150 words on how animals have adapted to living in Polar Regions.
