The TUNDRA

The TUNDRA

• Today I will learn about the Tundra because I
  need to know the characteristics that scientists
  use to classify the biomes.

General Description

• The Tundra is so cold that trees do not grow.
• The layer of soil just below the surface soil
  stays frozen all the time called PERMAFROST.
• The tundra is much like the desert because it
  does not receive much precipitation.

Location

• The tundra is located at the North and South
  Pole.

• Winter -26 degrees C (-15 degrees F)
• Average yearly Rainfall 30 to 50 cm

Adaptations of Animals and Plants

• Animals that live in the tundra usually have
  white fur to camouflage them with the snow.
• Also many of the birds migrate in the winter
  months.
• The plants are able to survive with very little
  water and are able to withstand high winds and
  very low temperatures.

Human Impact

• Due to hunting and over development of land,
  humans have caused the extinction or near
  extinction of several Arctic species.
• Human pollution and over consumption is also
  causing great damage to the Arctic ecosystem.
