What are characteristics of the tundra?

Tundra winters are long, dark, and cold, with mean temperatures below 0°C for six to 10 months of the year. The temperatures are so cold that there is a layer of permanently frozen ground below the surface, called permafrost. This permafrost is a defining characteristic of the tundra biome.

What is the temperature in tundra?

The Arctic tundra, where the average temperature is -30 to 20 degrees Fahrenheit (-34 to -6 degrees Celsius), supports a variety of animal species, including Arctic foxes, polar bears, gray wolves, caribou, snow geese, and musk oxen.

Why is the tundra biome important?

This frozen ground has proven vital to tracking climate change through the centuries, as any temperature change leaves its mark on the permafrost. Permafrost has also alerted scientists to the rapid environmental changes happening since the industrial revolution.

Does it rain in tundra?

Tundra regions typically get less than 25 centimeters (10 inches) of precipitation annually, which means these areas are also considered deserts.

What kind of animals live in the tundra biome?

Animals found in the tundra include the musk ox, the Arctic hare, the polar bear, the Arctic fox, the caribou, and the snowy owl. Many animals that live in the tundra, like the caribou and the semipalmated plover, migrate to warmer climates during the winter.

What is the soil like in the tundra?

The soil in the Arctic is largely permafrost or soil that remains frozen year-round, leaving only a thin surface layer of thawed soil in summer for plant roots to grow in. Tundra soil is also scarce in many of the nutrients that plants need to grow.

How do plants survive in tundra?

Plants also have adapted to the Arctic tundra by developing the ability to grow under a layer of snow, to carry out photosynthesis in extremely cold temperatures, and for flowering plants, to produce flowers quickly once summer begins. A small leaf structure is another physical adaptation that helps plants survive.

What do people in tundra eat?

These traditional Inuit foods include arctic char, seal, polar bear and caribou — often consumed raw, frozen or dried. The foods, which are native to the region, are packed with the vitamins and nutrients people need to stay nourished in the harsh winter conditions.
