ÁLVARO POLO & SEBASTIÁN SALVATIERRA

2. LOCATION

5. CARACTERISTICS- The Tundra has extremely cold climate :
- Two main seasons, winter and summer.
- Winter is long (about 6 to 10 months), very cold and
dark, with the average temperature around −30
°C .
- Summer is short, and daytime temperatures rise
about 12 °C.
-
- There is very low diversity
-
- The vegetation structure is simple: The permanent
frozen soil does not make tundra a favorable place for
plants to grow
-
- Huge absence of trees: the tundra’s frozen floor,
called permafrost, prevents deep root growth that would
support lofty structures like trees.
- Antartic
