Perhaps the most famous feature of the tundra is its permafrost, referring to land that never thaws. While the surface layer of soil in the tundra does thaw during the summer - allowing plant and animal life to thrive - there is permanently frozen soil beneath this layer.

What is the importance of tundras?
The Tundra plays a large role in the temperature regulation of the planet. As warm air rises from the tropical zone it is cooled in the Tundra causing it to sink back down to the equator. This causes weather and air currents. Without this system climate as we know it would change drastically around the world.
What is a interesting fact about tundra?
The tundra biome covers about 20% of the Earth. Although Antarctica is not located in the Arctic Circle, it is considered to be a part of the tundra biome because of its very harsh temperatures. The tundra biome is the driest place on Earth. Rainfall averages ten inches a year.
What makes the tundra interesting?
Low temperatures, permafrost, and little nutrients in the soil prevent most forms of vegetation from growing. The tundra offers some beautiful views and interesting wildlife for visitors willing to brave the arctic cold.
What is the human impact on the tundra?
Humans have changed the landscape through the construction of residences and other structures, as well as through the development of ski resorts, mines, and roads. Hunting, oil drilling, and other activities have polluted the environment and have threatened wildlife in tundra ecosystems.
How do tundras affect the world?
Warmer tundras could also see increased risk of wildfires and drought—scientists have documented a significant disappearance of lakes in western Greenland between 1969 and 2017. Air pollution affects tundra environments in different ways. ... Air pollution can also harm or kill the important food source of lichen.
Is the tundra wet or dry?
Still, the tundra is usually a wet place because the low temperatures cause evaporation of water to be slow. Much of the arctic has rain and fog in the summers, and water gathers in bogs and ponds. Vegetation in the tundra has adapted to the cold and the short growing season.
How would you describe the tundra?
Tundra ecosystems are treeless regions found in the Arctic and on the tops of mountains, where the climate is cold and windy, and rainfall is scant. Tundra lands are covered with snow for much of the year, but summer brings bursts of wildflowers.
Is the tundra a desert?
The tundra is a treeless polar desert found in the high latitudes in the polar regions, primarily in Alaska, Canada, Russia, Greenland, Iceland, and Scandinavia, as well as sub-Antarctic islands. The region's long, dry winters feature months of total darkness and extremely frigid temperatures.
Why is the tundra called the Land of the Midnight Sun?
The polar regions are called the "lands of the midnight sun" because in the summer, the sun never sets. ... As the Earth orbits around the Sun, that tilt makes the North Pole face towards the sun in summer (keeping it in sunlight even as the Earth spins) and away from it in winter (keeping it dark).
How cold is it in the 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.
Can humans live in tundra?
Humans have been part of the tundra ecosystem for thousands of years. The indigenous people of Alaska's tundra regions are the Aleut, Alutiiq, Inupiat, Central Yup'ik and Siberian Yupik. Originally nomadic, Alaska Natives have now settled in permanent villages and towns.
What is the most famous tundra?
Claiming the most northern reaches of land on our planet, the High Arctic tundra of northern Greenland, or Kalaallit Nunaat as it is known locally, is a unique and fragile ecosystem.
Can I go to Arctic?
Most people fly to the Arctic, but you can get there by ship, or even car! Although flying is quickest, and cheap regular flights make the Arctic easily accessible, the adventure of the journey is far greater on an expedition vessel.
