Tundra Climate (E) 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

For example‚ terrain types‚ bodies of water‚ natural units (consisting of all plants‚ animals and micro-organisms in an area functioning together with all of the non-living physical factors of the environment) are natural geographical features.

BIOMES LAB BIOL 120 `` A biome is a major complex of similar communities. It is the largest ecological unit we recognize. Different books vary in the number of biomes they list. Temperature and precipitation are the two key factors that determine the different type biomes. Some books consider marine ecosystems and freshwater systems as biomes. Others break out wetlands as a biome. We will look at 10 terrestrial biomes: 1. Tundra (Arctic and alpine) 2. Boreal forest or taiga

adapt to survive in these conditions. This biome is similar to tundra and deciduous forest‚ but there are some differences. The differences between the coniferous forest and tundra: In the tundra‚ it is windy like the coniferous forest. In the coniferous forest‚ it rains and snows. In the tundra‚ there are about two months of frost-free days. In the coniferous forest‚ there are about fifty to one hundred frost-free days (as said in the ‘introduction’). The tundra has very less trees than coniferous forest

Succession often leads to a faily stable collection of organisms called a climax community. Land Biomes A biome is an environment that has a charcteristic climax community. The Earth is made up of two main biomes: land biomes and aquatic biomes. The major biomes are the tundra‚ taiga‚ temperate decidous forest‚ grassland‚ tropical rainforest‚ and desert. Tundra Tundras are the northermost biomes. They have nearly no tress and are covered
