1. The World’s Biomes

2. What is a Biome? Areas of the Earth that are defined by: Climate
Geography
Precipitation
Vegetation
Species variety

4. Tropical Rainforest Dense vegetation Wide variety of species
Tall trees
Little light reaches forest floor
Hot, humid climate
Rainfall: 155 in./yr.
Temp: 34°C

5. Grassland Also called prairies or plains Wide variety of grasses
Limited variety of species because of protection
Rainfall: 20 in./yr.
Temp: 30°C

6. Desert Rainfall: less than 10 in./yr. Temp: 38°C
Very limited species and vegetation variety
Cacti and reptiles

7. Deciduous Forest
Hardwood trees, that shed their leaves in autumn (Why?)
Four distinct seasons
A fair variety of species
Rainfall: 40 in./yr.
Average temp: 28°C

8. Tundra Permafrost Extremely cold winter climate Very little vegetation
Limited species variety
Rainfall: 15 in./yr.
Temp: 12°C – (-26°C)
Alpine: above tree line of very high mts.

9. Coniferous Forest (taiga)
Coniferous trees
Fairly limited variety of plants and animals
Cold winters, warm summers
Wet climate all year round
Rainfall: 23 in/yr
Temp: 14°C

10. Savanna Dry winters, wet summers Warm temps, but not extremely hot
Limited plant and vegetation variety
Good species variety
Rainfall: 59 in./yr.
Temp: 25°C

11. Make a Graph!
Create a bar graph of the average rainfall of each biome.
