Tundra
Tundra is…

A treeless area between the icecap and
the tree line of Arctic regions, having a
permanently frozen subsoil and supporting
low-growing vegetation such as lichens,
mosses and stunted shrubs.
Geographic Location

The tundra is located around the North
Pole in the arctic cycle. For most of the
year it is covered in snow. The layer of
earth beneath the Tundra is frozen all year
long. This is called the permafrost.
Climate

The tundra is the coldest region in the
world. Fierce winds blow while snow and
ice cover the ground. Even the sea freezes
as the temperature gets colder. The tundra
receives less than 10 inches of
precipitation yearly. The tundra has a
short summer, the temperature only rises
to about 50 degrees Fahrenheit. The
awerage yearly temperature is only 10 or
20 degrees Fahrenheit.

Human Impact

Humans have altered the Arctic Tundra
through resource exploitation, fire
management, and altered grazing regimes
because of the constantly changing
patterns of reindeer husbandry.
Additionally, humans have been polluting
these areas with chemicals, gases and oils
which is threatening the lives of Arctic
animals.
