The natives of the North-American tundra are known as The Eskimos.

The northern part of the continents within the polar region is known as the Tundra region. Tundra regions are found in the northern and southern hemispheres between the ice-covered poles and the coniferous forests. In the north, this biome stretches across northern Canada and Alaska, Siberia and northern Scandinavia, on or close to the Arctic Circle. There are also areas of tundra in coastal Antarctica.

Due to the cold, the upper soil surface of the tundra region is frozen into a rock-like state all through the year. This is called permafrost. It comprises 24% of land in Northern Hemisphere. A massive amount of carbon is found in permafrost. Structurally, permafrost is important. Erosion, disappearance of lakes, landslides, and ground subsidence is caused by the melting of permafrost. It also causes changes in composition of plant species at high altitudes.

Tundra has cold and dry Climate. It is covered with snow and is very cold throughout the year. There is no sunshine in the winter season of the year, both days and nights are dark. In the month of February-March, the sun begins to shine. Sun shines for the whole day and night. This tundra region is also known as the land of the midnight sun. There are nearly six months' day and six months' night in the tundra region.
