6 TUNDRA: Fact sheet  Located at latitudes around the north and the south pole.  Little precipitation- less than 25 cm/yr.  Covered with ice most of the year.  Winters are 6 to 9 months long/ summers are short.  Covered with permafrost (permanently frozen soil)

11 Taiga Biome  Located at latitudes between 50 – 60 degrees north.  Precipitation between cm each year.  Covered with cone bearing trees called coniferous trees. Very similar to pine trees  Very long cold winters that last more than 5-6 months.  No permafrost. The ground thaws!!

19 Temperate Deciduous Forest  Located at latitudes below 50 degrees North.  Have four seasons each year. Summer, Spring, Winter, and Fall  Precipitation ranges between cm/ yr.  Winters are cool and summers are warm.  Covered with deciduous trees (trees that lose their leaves).  Found in the eastern United States

24 Tropical Rain Forest  Located near the equator.  Average rainfall 200 to 225 cm/ yr.  Warm temperatures most of the year- hot and humid climate.  Contains over 700 species of trees and 1000 species of flowering plants.  Contains the most variety of animal species compared to every other habitat.  Most of the world’s medicine comes from the rain forest

29 Grassland Biome  Precipitation between 25 and 75 cm/yr.  Covered with communities of grasses.  Have large root systems that can withstand drought conditions.  Rich and fertile soil.  Home to grazing animals and farmland.

34 Desert Biome  Driest biome on earth. Less than 25 cm of rain per year.  Located near 30 degree North and South latitude.  Animals and plants have special adaptations for survival.  Rain is quickly drained away or evaporated.

41 Antarctica  It is the largest desert on earth  It is a desert because it receives less than 10” of precipitation per year  The ice at Antarctica is nearly 3 miles deep
