What is a Biome?

• Biome- is a group of land ecosystems with similar
  climates and organisms.
• What is an ecosystem?
• An ecosystem is a community of organisms that
  live in a particular area, along with their
  nonliving surroundings

Climate

• Climate vs. Weather whats the diff?
• Climate The typical weather pattern in an area
  over a long period of time
• Weather the condition of Earths atmosphere at
  a particular time and place
• Factors contributing to climate
• Average rain fall
• Average temperature
• Average amount of sunlight during seasons

Temperate Rainforests

• The word temperate means mild temperatures.
  Rainforests receive lots of rain. Average annual
  temperatures are between 39 F and 54 F (4-12
  C). Annual rainfall is about 5 to 16 feet.

Majority of the worlds temperate rainforests
can be found along the Pacific Coast of North
American stretching from Oregon to Alaska, some
can also be found on the Southeast coast of
Chile, and a few others can be found on the
coasts of the United Kingdom, Norway, Japan, New
Zealand, and southern Australia

Tropical Rainforest
11
Tropical Rainforests

• This biome is usually located near the equator.
  The temperature is warm and precipitation is
  high. Between 4 and 22 ft of rain fall each
  year. Average temperature is between 68F and
  93F ALL YEAR!

57 of all tropical rainforests are found in
Latin America. One third of the world's tropical
rainforests are in Brazil. Other tropical
rainforests are located in Southeast Asia and the
Pacific Islands (25 of the world's tropical
rainforests) and West Africa (18).
18
Desert
19
Desert

• The desert is an area that receives less than 25
  cm of rainfall a year. The climate is usually
  hot and dry.

20
Although most deserts, such as the Sahara of
North Africa and the deserts of the southwestern
U.S., Mexico, and Australia are hot, another kind
of desert, cold deserts, occur in the basin and
range area of Utah and Nevada and in parts of
western Asia.

Grasslands
23
Grassland

• The temperature is moderate and little
  precipitation. An area populated by grasses and
  other non wood plants because there is not much
  rain. The precipitation is so inconsistent that
  drought and fire prevent large forests from
  growing.

24
Savannahs are warmer grasslands (tropical) and
they cover almost half of Africa. Temperate
grasslands, commonly called prairies or steppes
have more varyingtemperatures and can be found in
South Africa, North America, Hungary, Argentina,
and Uruguay.
25
Deciduous Forest
26
Deciduous Forest

• Trees in this biome shed their leaves and grow
  new ones each year. Rainfall (30 60in.)and
  temperatures (50F) are moderate

Deciduous biomes are located primarily in the
eastern half of the United States, Canada,
Europe, parts of Russia, China, and Japan.
29
Tundra

• This area is extremely cold and dry!

30
Tundra

• Since the tundra is so cold, most of the soil is
  frozen all year called permafrost. Plants are
  especially hardy to grow here.

31
The tundra is located around the North Pole in
the Arctic Circle
32
Tiaga (Boreal Forest)
33
Taiga (Boreal Forest)

• Similar to the tundra, but not as bitterly cold
  all year. The taigas climate is cool (very cold
  in winter, moderately warm in the summer). The
  dominant trees are coniferous trees.

34
Most of Canada and Russia are covered in
Taiga/Boreal Forrest.
