Atmosphere and Climate
The Tundra is the coldest and driest biome. The percipitation is only about 6-10 inches a year, this precipitation consist of mostly snowfall. The Tundra is a windy place and winds can be up to 30 to 60 miles per hour. The tundra is basically a desert when it comes to precipitation.
Location and Appereance
The Alpine is usually located at lattitudes 55 degrees to 70 degrees north. In this area it is mostly a vast and treeless land that covers about 20% of the earth's surface. During summer the top layer of soil may thaw out long enough to let plants grow out and reproduce. Water from melting permafrost and snow forms lakes and marshes each summer.
The Tundra contains about 48 spicies of land animals, although there isn't a lot of biodiversity. The animals consist of modified shrews. hares, rodents, wolves, foxes, bears, and deer. Polar bears are predators of the Tundra. There are huge hurds of caribou in North America. There aren't many spicies of insects in the Tundra, but black flies, deer flies, and mosquitoes can make the Tundra a misreable place during the summer.
Over View and Contribution to water cycle
There are many things to say about the Alpine Tundra, this area is the driest and coldest of all biome. There is very little water due to the climate. The Tundra contains little fresh water during the summer. The water thaws out and causes little lakes. Lakes are large bodies of fresh water surrounded by land. The water cycle is limited in the area.
