A taiga is a forest biome consisting mostly of
cone-bearing evergreen trees that only exists in Month
the northern hemisphere.
Tundra Biomes
It occupies more space on Earth’s continents
than any other biome. A tundra biome is cold, dry, and treeless.

Winters are long, dark, and freezing, and summers
are short and cool. The growing season is only
50–60 days.

Winters are long and snowy and summers are short,
warm, and moist.
Permafrost is a layer of permanently frozen soil that
prevents deep root growth.
Many animals hibernate or migrate south during
winter. Few animals live in tundras year round.

Drilling for oil and gases can interrupt migration
patterns.
