Have you ever seen an elephant rumble down the street in Wenatchee, Washington? Or have you heard of a polar bear living in an Arizona desert? Outside of a zoo - probably not!

Around the world there are many different areas called Biomes. The amount of water, soil, climate conditions, plants and animals that live there distinguish one biome from another.

Biomes of the World
	Tundra Tundra is the coldest of all the biomes. It has poor soil, little rain and few trees. Artic Tundra and Alipine Tundra
	Desert About one-fifth of the Earth's surface is covered by Deserts. Hot and dry, semiarid, coastal and cold are four types of deserts.
	Forests Forests cover about one-third of the earth's land. Conifer (or tiaga) Deciduous, tropical rain and temperate rain are some different types of forests.
	Grasslands Areas that are too dry for a Forest, but not as dry as a desert are called Grasslands. Praries and Savannahs are two types of grasslands.
	Marine Covering two-thirds of the earth, this is the largest biome.
