• Large geographic areas with similar climax
Factors that Determine Climate
• Temperature
• Latitude
– Zero latitude at the equator
– 90° latitude at the poles
– The higher the latitude the lower the suns energy
• Elevation
– The distance above sea level
– Atmosphere acts as insulation
• Precipitation
• The amount of moisture that condenses
and falls to the earth as rain.
Terrestrial Biomes(land)
• Tundra
– A treeless area between the icecap and the tree line
of Artic regions, having a permantly frozen subsoil(Permafrost) and supporting low growing
vegetation. Little precipitation
Taiga( Northern Coniferous Forest)
• Sun-artic, evergreen coniferous forests of sub-artic
lands, covering vast areas of North America and Eurasia
• Dominated by fir and spruce trees
Temperate Deciduous Forest
• Found in the northern and southern
• Latitudes below 50°
• Four distinct seasons
• Temp range –0 to 30°C
• 75 to 150cm of precipitation
Tropical Rainforest
At the equator
Lush green plants
200 to 400cm of rain per year
Constant temp of 25°C
Hot and humid
Temperate and tropical regions
25-75 cm of rain a year
Good farming area
Dry season
Arid region
Less than 25cm of rain per year
Sparse or no vegetation
Covered in sand or gravel
Aquatic Biomes(water)
• Two types of water biomes
– Freshwater
– Marine
Freshwater Biome
• The aquatic biome consisting of water containing fewer
salts than the waters in the marine biome; divided into
two zones: running waters (rivers, streams) and standing
waters (lakes, ponds).
Marine Biome
• The aquatic biome consisting of waters
containing 3.5% salt on average; includes the
oceans and covers more than 70% of the Earth's
