24. TUNDRA The world's youngest biome -- It was formed 10,000 years ago. Located at latitudes 55° to 70° N, the tundra is a vast and treeless land which covers about 20% of the Earth's surface, circumnavigating the North pole. It is usually very cold, and the land is pretty stark. Tundra comes from the Finnish word "tunturia", which means a barren land.

25. http://www.blueplanetbiomes.org/ TAIGA • Taiga is the Russian word for forest and is the largest biome in the world. It stretches over Eurasia and North America. The taiga is located near the top of the world, just below the tundra biome. The winters in the taiga are very cold with only snowfall. The summers are warm, rainy, and humid. A lot of coniferous trees grow in the taiga. The taiga is also known as the boreal forest.

26. GRASSLANDS The STEPPE biome is a dry, cold, grassland that is found in all of the continents except Australia and Antarctica.

27. DECIDUOUS FORESTS

28. The CHAPARRAL biome is found in a little bit of most of the continents - the west coast of the United States, the west coast of South America, the Cape Town area of South Africa, the western tip of Australia and the coastal areas of the Mediterranean. Also called MAQUIS, SHIBLYAK, BUSH..

31. The TROPICAL RAIN FOREST is a forest of tall trees in a region of year-round warmth. An average of 50 to 260 inches (125 to 660 cm.) of rain falls yearly.

32. ALPINE biomes are found in the mountain regions all around the world. They are usually at an altitude of about 10,000 feet or more.
