Geographical Location -The Arctic tundra can be found in Antarctica and the North Pole. It can also be found in Northern portions of Canada, Alaska, Greenland, the United States, and Finland.
Climate. The tundra is a bleak and treeless place. It is cold through all months of the year. Summer is a brief period of milder climates when the sun shines almost 24 hours a day. It has been called "the land of the midnight sun". But even the sun can't warm the tundra much. The short summer lasts only 6 to 10 weeks. It never gets any warmer than 45 or 50° F. The warmer weather causes a layer of permafrost, ice that never goes away in the ground, to melt, creating bogs and shallow lakes that don't drain. They breed stinging insects, which make life even in the summer miserable for the inhabitants of the tundra. The wind blows constantly, whipping around the small plants.
Food web. The Arctic food web, everything is in order and the biggest predator is man.
Vocabulary Permafrost, is soil that remains frozen through the year.
