1. What are the characteristics (weather/temperature) of this biome?
Tundra At latitudes just south of the north pole
or at high elevations, a biome can be found that
receives little precipitation but is covered with ice
most of the year. The tundra is a cold, dry, treeless
region, sometimes called a cold desert. Precipitation
averages less than 25 cm per year. Wint
Arctic can be six to nine months long. For some of
these months, the Sun never appears above the
horizon and it is dark 24 hours a day. The average
in the
daily temperature is about -12°C. For a few days
during the short, cold summer, the Sun is always
visible. Only the top portion of soil thaws in the
summer. Below the thawed surface is a layer of per-
manently frozen soil called permafrost, shown in
Figure 6. Alpine tundra, found above the treeline
on high mountains, have similar climates. Tundra
soil has few nutrients because the cold tempera-
tures slow the process of decomposition.
