1. Describe three similarities (biotic or abiotic) between the Artic and Antartic tundra. Describe the difference: course hero
Similarities:
a) Both Arctic and Antarctica have glaciers, icebergs and snowstorms and receive the lowest precipitation in the world.
b) Both the Arctic and Antarctica have seals, birds, and fish.
Differences:
c) Antarctica is colder and windier than in the Arctic. The lowest temperature ever measured, -89.2°C, was registered Vostok in Antarctica on 21 July 1983 (Kranz). The positioning of the Antarctica renders it lightless since no sun rays reach the region making it extremely cold than the Arctic
d) Antarctica has no mammals that live on land. In the Arctic, several land-based mammals can be found, including reindeer,
B. Why is it colder at the poles than at the equator? The reason why is because the Sun’s rays hit those areas with the least amount of rays. They are also faced away from the sun the most compared the other areas meaning they will get the least of the Sun’s rays.
Antarctica has one of the only two polar ice caps on the planet Earth. It is called the Antarctic ice sheet and it covers about 98% of the Antarctic continent. Wikipedia says this is the largest ice mass on Earth; it covers about 5.4 million square miles, and is
2. The higher the elevation, the colder the air and therefore, the colder the climate.
Polar bears are just one kind of animal you can find on the tundra did you know the tundra is the coldest biome of them all? The climate, producers, and consumers, are all parts that make up the tundra.
The Tundra is an extremely cold climate. During the winter months the average temperature is -34 degrees Celsius. The Arctic tundra is located in north Russia. Its coordinates are anywhere between 60 to 80 degrees North latitude and 70 to 180 degrees east longitude. The average precipitation including melting snow is 6 to 10 inches. The arctic tundra has a cold and dry climate but underneath the top layer of soil is a solid layer of subsoil called permafrost which never thaws.
Almost a third of Alaska lies within the Arctic Circle. It has a very cold average temperature and much of its land is covered in permafrost.
On February 7, 2012 Russian scientist discovered a “golden-like swastika” in an Arctic ancient lake that hasn’t been touched, in what they believe, 20 million years. As the old conspiracies of German activity in the South Pole returns, with a vengeance, citizens spark fear across the country of Russia. Little is known about the vast frozen tundra that resides in the far south, for Antarctica is a place of mystery and wonder.
Climatic fluctuations led to major changes in the Arctic geography, effectively increasing the diversification of high-latitude organisms, including the lagomorphs that lived in those latitudes, in the Pleistocene. The organisms expanded into the new available habitats while the glaciers receded. One of these refugiums, Beringia, in Arctic North America during the glacial maxima, has been subjected to extensive research while many other refugiums have been hypothesized such as a High Canadian Arctic refugiums (Waltari et al. 2005). Furthermore, during the last glacial maximum some coastlines in the High Canadian Arctic were ice free (Waltari et al. 2005). Eurasia was less glaciated than North America during the glacial maxima, yet a large sheet
This zone encounters low measures of precipitation and to a great degree frosty temperatures for a large portion of the year. The ice tundra
Antarctica is the coldest, driest, and most inhospitable continent on Earth. Yet it is yields some 90 percent of the Earth most precious natural resource: water. But behind this pristine exterior, Antarctica is fighting a losing battle. New data suggests that the continent as a whole is warming at an alarming rate. According to recent studies gathered from Nature Magazine, the western half of the continent is warming five times faster than any other place
The Arctic and Subarctic areas included present-day Alaska, as well as Canada and Greenland. These areas were
There are five major biomes: deserts, grasslands, forests, aquatic, and tundra. The arctic tundra is one which has a frigid climate, whereas a desert is known to be extremely hot most of the year (UCMP. 2016). This is where opportunities are abound for biologists as one who does not appreciate the extreme heat, or has water phobias can study a grassland tundra. What is remarkable is the common species some may have that adapted to the biome. In fact, there are polar bears that live in the tundra and black bears that live in the in the forests. They are both bears; however, a polar bear has adapted to the extreme cold with very thick fur and is white to blend in with the snow. A black bear would not thrive in the arctic tundra as it has adapted to surviving in a forest setting with more moderate
Antarctica is the Earth’s southernmost continent, it is responsible for the frigid temperatures that have a cooling effect on our atmosphere. The centrally located tropical waters derive their source of heat from the sun; together these two bodies of water combine to regulate our ecosystem. Quite alarming, this delicate temperature balance is at stake due to interference from humankind
low temperature. There is two types or tundras, Alpine and Arctic. Permafrost is located in a
The flat treeless lands that forms a ring around the Arctic Ocean are known as Tundra. The climate sub region is also called as Tundra. It is exclusively located in the Northern Hemisphere. The fall of precipitation is very less here and is usually less than 15 inches per year. This land has permafrost that is the subsoil is constantly frozen. In the summer that lasts for only a few weeks and the temperature may reach slightly above 40O
