Transcript of Terrestrial Biomes (Brianna Elliott)

Terrestrial Biomes 3.2 Ecosystems on land are grouped into biomes that are based on the plant communities within them. These are Terrestrial Biomes Weather is the condition of the atmosphere at a specific place and time, therefore, the weather differs by location. But what causes theses variations? Latitude Run horizontally latitude lines are also known as Parallels because they are parallel to each other Run vertical and are also called meridians Longitude They become more wide at the equator Because light from the sun strikes earth more directly at the equator than at the poles, earth's surface is heated differently. These zones are refereed to as Polar, Temperate and Tropical zones An area's latitude has a very large impact (along with other factors) on what the climate will be in that region. If latitude didn't exist, the biomes would be spread out equally upon the earth.

Climate is the average weather condition in an area Tundra Dessert Polar Region Mountains Temperate Woodland and Shrubland Temperate Grassland Tropical Savannah Boreal Forest Tropical
Seasonal
Forest Tropical Rainforest Temperate
Forest The tundra is a treeless biome
with a layer of permanently
frozen soil below the surface
called permafrost Tundra biomes can be found in
many regions such as:

North America
Europe
Siberia
Asia Tundra Facts:

Tundras are the youngest biome
Tundra biomes are located south of the polar ice caps in the Northern Hemisphere
Trees cant survive in the Tundra biome
The average temperature range is
-34 degrees to -12 degrees
Because of the permafrost, is is cold and dark much of the year Animal Species
native to Boreal Forests We're cute! Animals species native to the Tundra Animal Species Native to Deserts Desert Facts:

A desert is any area in which the annual rate of evaporation exceeds the rate of precipitation.
Deserts are home to a variety of plants and animals
The temperature range for desserts are 20 degrees to 49 degrees at the highest and -18 degrees to -10 degrees at the lowest
Also, the temperatures vary and the amount of rainfall is low Deserts can be found on every continent except Europe Tropical Savanna Facts:

Tropical savannas receive less rainfall than other ares (50-130) cm per year
Tropical Savannas are home to many trees, plants and lots of grass
The average temperature range is 20 degrees to 30 degrees Tropical Savanna biomes can be found in many areas such as:

Africa
South America
Australia Animal Species Native to Tropical Savannas Animals Native to Tropical Seasonal Forest Facts about the Temperate Animal Species native to Woodlands and Shrublands Facts about Temperate Woodlands and Shrublands:

These regions have less annual rainfall than temperate forests
They are dominated by shrubs called chaparral
The summers are very hot and dry
The winters are cool and wet
Temperate Woodland and Shrublands can be found in many areas such as:

Around the Mediterranean Sea
Western coast of North and South America
South Africa
Australia
Animal Species Native to the Tropical Rainforests Facts about Tropical Rain Forests:

These regions are warm with lots of rainfall
The most diverse of all biomes
The temperature range is from 24 degrees C to 27 degrees C
Included in this biome are tall, broad-leaved trees, mosses, ferns, shrubs and plants
Also, there are shorter trees that make up the understory of a tropical rain forest
Tropical Rain Forests are located in the following places:
Central and South America
Southern Asia
Western Africa
Northeastern Australia
