What are biomes?

Biomes are large geographical areas that have similar climates and ecosystems.

The biomes:

Tundra Taiga Temperate deciduous forest Tropical Rain forest Grassland Desert

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)

Tundra Biome

Tundra Biome

Taiga Biome

Located at latitudes between 50 – 60 degrees north.

Precipitation between 35-40 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!!

                                                 

                         

Taiga

Taiga

Temperate Deciduous Forest Located at latitudes below 50 degrees

North. Have four seasons each year. Summer,

Spring, Winter, and Fall Precipitation ranges between 75-150 cm/ yr. Winters are cool and summers are warm. Covered with deciduous trees (trees that

lose their leaves). Found in the eastern United States

Temperate Deciduous Forest

Temperate Deciduous Forest

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

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.

Grassland

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.

                                     

Deserts

                                             

Desert

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
