Geographical location Antarctica is one of the two continents that are wholly in the southern hemisphere. 42 % of Antarctica is owned by Australia, the other 58% is spread across six other countries. All seven countries have agreed to the Antarctic Treaty, which makes laws to prevent pollution and other bad things. Antarctica’s
Exploring Antarctica Map of AntarcticaAntarctica is the fifth largest of the seven continents. It is situated over the South Pole almost entirely south of latitude 66°30’ south (the Antarctic Circle). It is a very rough circular shape with the long arm of the Antarctic Peninsula stretching towards South America. There are two large indentations, the Ross and Weddell seas and their ice shelves. The nearest other land masses are South America 600 mls / 1000 km away across the roughest stretch
Antarctica is a land of the extremes. As the coldest and driest continent on Earth, it has the highest average elevation. As the fifth largest continent in the world, Antarctica is most commonly known as the "South Pole". Ninety-eight percent of this landmass is covered by ice sheets to with an average depth of 1.25 miles has the coldest temperature on record. In recent decades the whale and seal population has begun to recover, but interest has grown in new resources, especially oil, minerals
Researchers have a number of questions that they hope to answer by investigating Antarctica. The Earth’s southernmost continent is composed of land that is completely encircled by ocean and in most places, is covered by ½ mile of glacial ice. Sometimes called a polar desert, Antarctica is the most arid of all the continents, with very little snow falling each year. Scientists wonder what type of land forms can be identified beneath the ice, how glaciers work, and if movement of under-ice rivers
wish to visit the frozen dessert at the bottom of our world, also known as Antarctica. However, this may come to an end. People believe that the cause of Antarctica melting is because of tourists. However, there are many arguments against this. The Antarctic is beginning to melt mainly because of the ships that leave many tons of emissions of carbon dioxide behind. Yet one study shows that the scientists that work on Antarctica cause more harm to the environment than tourists do. Tourists should also
Antarctica Location and Description of Ecosystem The ecosystem of Antarctica is located in the South Pole. The Antarctic is Earth’s southernmost continent, and is situated in the Antarctic region of the Southern Hemisphere, almost entirely south of the Antarctic Circle, and is surrounded by the Southern Ocean. Antarctica is a unique and large continent with many animals that have adapted to live in the harsh, cold climate. Exploration in the South Pole began in the 1800s, and has become an important
Considered the “bottom of the world” by most, Antarctica is often perceived as a barren, desolate tundra where there is little to no possibility of sustaining life. Being the “coldest, windiest, and driest continent on Earth,” one could easily imagine living on the Antarctic continent being near impossible (CIA 2018). However, the opposite can be found true of the southernmost continent. Antarctica boasts around 75 active research stations around the continent to support hundreds to thousands of
Dinosaur Fossils in Antarctica Millions and millions of years ago the continents lay together as one super-continent known as Pangea. As time went on and the plates underneath the Earth began to separate, the continents land moved towards the poles where glaciation occurred. Glaciation is the process in which glaciers were formed during the ice age. Glaciation causes a drop in temperature which in turn causes water to freeze and form many layers of ice (http://palaeo.gly.bris.ac.uk/Palaeofiles/Permian/intro
Environmental Impact of Tourism on Antarctica This essay discusses the environmental impact of tourism on Antarctica. The subheading Description will give an overview of the continent, highlight the unique landscape, weather patterns and research stations making up some of the tourist attractions of this continent. The subheading Tourism in Antarctica gives an account of the type of tourist Antarctica attracts and their primary motive identifying scientific research staff as tourists as well
Living in Antarctica: Surviving or Thriving? Considered the “bottom of the world” by most, Antarctica is often perceived as a barren ice-land where there is little to no possibility of sustaining life. Being the “coldest, windiest, and driest continent on Earth,” one could easily fathom living on the Antarctic continent being near impossible (CIA 2018). However, the opposite can be found true of the southernmost continent. Amazingly, Antarctica boasts around 75 active research stations to support
There is less sea ice surrounding Antarctica today than there was since reliable records began in 1979. The director of the National Snow and Ice Data Centre, told US broadcaster CNN, recently. The extent to which the ice at the poles is melting is considered an indicator as well as a consequence of global temperature rises. (Ref: Thomos Reuters, thomsonreuters.com/en/press-releases/climatechange-ice 2017) Why is the Arctic melting faster than the Antarctica? A new report says the Arctic may be
Antarctica is the coldest and remote place on earth also it's very existence was questioned by navigators for centuries even after it was discovered after 1820 , this place was also known as "A land unknown". This analytical essay will talk about the Terra Nova Expedition by Robert falcon Scott and would focus on four points which caused this expedition to fail. 20th century was the race to travel to be the first person to stand on the south pole. Scott was chosen for this task and he wanted to go
Antarctica is the coldest place on earth, with temperatures at an average of -49°C, and it rarely ever gets above freezing. The reason why the Antarctic is so cold is because sunlight has to go through a thicker atmosphere to hit it as Earth is on an angle which also means the light rays are spread over a larger area than if they were hitting Antarctica directly. This means light is spread over a larger area thus not warming as much as it could. When sunlight does eventually meet Antarctica, a lot
is located on Antarctica. Because Antarctica is centered on the South Pole it receives very little sunlight, and is the coldest climate on Earth. Most of the life in Antarctica is marine life, such as krill, seals, whales, and penguins. The land is so barren and unforgiving that almost nothing can indefinitely live there. Most of the humans that come to the South Pole are scientists studying the area or tourists. Unlike the North Pole which is basically a frozen ocean, Antarctica is classified

Emperor penguins are native to the desolate land of Antarctic Location: 1. Antarctica, as many of you know, is in the southern hemisphere at the south pole. It occupies a space of 14 million square kilometers. 280,000 sq kilometers is ice-free, while 13.72 million square kilometers is covered in ice. The ice free zone, has no vegetation
Antarctica, the land of snow and ice, is just that. The Continent is covered with a thick ice sheet that reaches up to an average of 2,450m. The average altitude of the Continent is 2,300m, which is remarkably high compared to other continents. The average temperature is -10 degrees centigrade along the coast, but it decreases to -60 degrees centigrade inland and the lowest inland temperature is lower than -80 degrees centigrade. The extreme cold, strong winds and dryness in Antarctica have created
Global warming is being caused by humans, not the sun. What is global warming? Carbon dioxide and other air pollution that is collecting in the atmosphere like a thickening blanket, trapping the sun's heat and causing the planet to warm up. Coal-burning power plants are the largest U.S. source of carbon dioxide pollution -- they produce 2.5 billion tons every year. Automobiles, the second largest source, create nearly 1.5 billion tons of CO2 annually. The planet is changing faster than expected,
which are now listed as endangered species due to the destruction of their habitat and alteration of their food web. The earth’s polar regions are the ice-covered areas located at the northern and southern ends of the globe known as the Arctic and Antarctica respectively. Life in these regions are incredibly difficult thus there are few and specific species living there. The north pole; the Arctic is affected most by the increasing temperatures as it has been proven to be heating up twice as fast as
Alejandra Reyes Tyler D. Watson 10 March 2014 Climate Change: Polar Regions and Marine Mammals As a result of climate change, specifically rising temperatures, there have been increased changes in sea ice and sea level in the Polar Regions. The melting ice creates a positive feedback, more rapidly changing the environment for marine mammals such as pinnipeds and cetaceans. Negative health effects of changes in their environment depend on species sensitivity. Because the most obvious effects of climate
November 1929 his main way of exploring was by airplane and discovered the Marie Byrd Land in Antarctica. After completion of his first expedition he started a second one from 1933 to 1935 and successfully competed his exploration. There were many explorations in Antarctica run by Wilkins in 1929 to 1930, a Norwegian captain, Hjalmar Riiser-Larsen, explored 1929 to 1930 on the coast of East Antarctica from Enderby Land to Coats Land. The area was later claimed by Norway as Queen Maud Land. In November
