Biomes

A biome is a regional or global

community of

organisms.

Determined by:– Climate Conditions

• Latitude

• Altitude

• Bodies of Water

• Air Currents

• Topography

• Ocean currents

–All of the determine the average temperature and precipitation!

Determined by:–Plant

communities

•Precipitation

•Sunlight concentration

•Soil richness

Tropical savannah are warm through the year, with

definite dry and rainy seasons.

Temperate grasslands are dry and warm during the summer; most precipitation falls

as snow.

Desert biomes are characterized by a very arid climate.

–very low amount of precipitation

– four types: hot, semi-arid, coastal, and cold

The temperate forests have a long wet season

and relatively dry summer. Ferns and moss cover the

forest floor.

The boreal forest/taiga biome is located in cooler northern climates.

–boreal forest

–long winters and short summers

–small amount of precipitation Source: Environment Canada

Banff, Canada

The tundra biome is found in the far northern latitudes with long winters.

–winter lasts 10 months

–limited precipitation

–permafrost
