The Tundra About a fifth of the land surface of the earth is tundra. The tundra is found next to the icy zones in the arctic. The temperatures on the tundra are below freezing and can drop to as low as -70 degrees F. There are winds that can blow up to 100 miles an hour. Temperatures are so cold, the water in the ground freezes, up to a depth of 2000 feet or more. It can reach temperatures of up to 50 degrees F on a warm summer day. There are a few places where only a few inches on the top

ability to restore itself. Controlled by sedge, heath, willow, moss, and lichen. Plains that are pretty much alike, called alpine tundra, occur above the timberline in the high mountains of the world. Even the Antarctic area has a couple of its own arctic regions itself. The climate of the tundra is characterized by harsh winters. The average temperature in the tundra area is about –27 degrees. But what is even worse are the long night. At nights the lowest temperture recorded was –67.36 degrees

animals that live here are usually caribou snow hares snow foxes and polar bears all the animals with fur to resist the cold. The tundra is a cold, barren, place where no trees grow. It is home to some plants the most common are the bearberry, the arctic moss, the Caribou moss, the Diamond leaf willow, the Labrador Tea, the Pasque Flower, and the Tufted Saxifrage.

Biomes Tropical rainforest: * What: Hot and wet areas with broadleaved evergreen forest * Where: Within 5°N and S of the equator * Climate, limiting factors: High rainfall(2000-5000 mm yr-1), high temperatures( 26-28°) and high insolation, P>E rain washes nutrients out of the soil, so nutrients may limit plant growth * Structure: amazingly high levels of biodiversity: plants compete for light thus growing tall to absorb it, so there is a multi-storey profile to the forests

Arctic tundra occurs in the far Northern Hemisphere, north of the taiga belt. The word "tundra" usually refers only to the areas where the subsoil is permafrost, or permanently frozen soil. (It may also refer to the treeless plain in general, so that northern Sápmi would be included.) Permafrost tundra includes vast areas of northern Russia and Canada.[2] The polar tundra is home to several peoples who are mostly nomadic reindeer herders, such as the Nganasan and Nenets in the permafrost area (and
