The seven biomes of Earth are water, rainforest, tundra, desert, taiga, deciduous forest and grassland. A biome is a large geographical area classified by its distinctive group of plants and animals adapted to the environment. A biome may go by a different name according to the continent on which it is found.
Water as a biome is either freshwater or saltwater. A rainforest, or jungle, is a thick, wet and warm forest, and it can be tropical or temperate. A tundra is coldest of all the biomes. Arctic tundras are found near the North Pole, and alpine tundras are on mountain tops all over the world. The word "tundra" derives from a Finnish word for "treeless plain" as this biome does not have trees, and the ground is always frozen.
A desert is a dry area where less than 19 inches of rain falls each year. The taiga biome is also known as boreal forest and is the largest land biome. It has short, warm summers and long, cold winters. The soil lacks nutrients, and evergreen conifers make up the majority of the plant life. Deciduous forests are found between the Arctic regions and the tropics. Deciduous trees lose their leaves in the fall and bud new ones in the spring. Grasslands are big open areas with few trees. They receive less rainfall than a rainforest but more than the desert.
