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 of water in the world - the Drake passage,
Australia is 1550 mls / 2500 km away, and South Africa 2500 mls / 4000
km away.
The total surface area is about 14.2 million sq km (about 5.5 million
sq mls) in summer, approximately twice the size of Australia, half as
big again as the USA and fifty times the size of the UK.
In the winter Antarctica doubles in size due to the sea ice that forms
around the coasts. The true boundary of Antarctica is not the
coastline of the continent itself or the outlying islands, but the
Antarctic Convergence.
2/ Why is Antarctica considered to be a desert?
A Desert is defined as a region that has less than 254 mm (10 in) of
annual rainfall or precipitation. Antarctica can be classified as a
desert by this definition. In the interior of the continent the
average annual precipitation (in *equivalent of water) is only about
50 mm (about 2 in), less than the Sahara. Along the coast, this
increases, but is still only about 200 mm (8 in) in *equivalent of
water. Heavy snowfalls occur when cyclonic storms pick up moisture
from the surrounding seas and then deposit this moisture as snow along
the coasts.

...the ice finally warms up sufficiently to melt. These
animals live largely in the Antarctic Peninsula.
The oceans surrounding the continent on the other hand are teeming
with great quantities of life. Large numbers of whales feed on the
rich marine life, especially krill. Six species of seals and 12
species of birds live and breed in the Antarctic. Crabeater seals are
the second most numerous large mammal on the planet after humans and
the population of krill has bee estimated as outweighing the human
population.
The most famous inhabitant of Antarctica has to be the penguin. A
flightless bird, but excellent swimmer, penguins live on pack ice and
in the oceans around Antarctica. They breed on the land or ice
surfaces along the coast and on islands. Best known and most typical
are the Adélie and emperor penguins.
Swimming to Antarctica, by Lynne Cox, is about Lynne’s adventure to become a great long distance swimmer. Lynne started as a slow swimmer. During practice, she never rested for each instruction the coach gives. She later found out that she wanted to be a long distance swimmer. Her coach told her to join a race on a lake. She went and she loved to swim in the open waters. She then went to a different program that trained her to swim in the open waters.
Space travel began in the 1960s with sending humans on single missions into space. Rockets launched into the air and just the tip would land in the ocean after parachuting back to Earth ("Space Shuttle Program," par. 4). The focus of space exploration changed during the 1980s; shifting from the desire for human space flight to the desire to create a reusable spacecraft. Originally called Space Transportation System (STS), NASA created the Space Shuttle Program (SSP) (Heiney, par. 1-2). It wanted a shuttle that was more economical because it could be launched, landed and relaunched and could gather better information. The 1980s began a new era in space exploration and had one the biggest tragedies in the history of space travel.
Throughout this exhibition the term exploiting will refer to benefiting from. Also, this exhibition will explore some of the ways, that people have been exploiting Arctic resources, for the last 4500 years. It will begin by explaining the location of the Arctic, and what indigenous people did to survive. Followed by, why Europeans went there, and what Arctic states are doing at present.

In 1914, a great leader began a great expedition, unbeknownst to him that instead of being known as great explorers, they would be known as some of the greatest survivors. This man was Sir Ernest Shackelton and he was determined to be the first to cross the Antarctic. Little did he know, his biggest challenge would end up being his ability to lead his team to survival. He also had no idea that their tale of strength, determination, and courage to survive would influence people well into the 21st century, and the book detailing their stories would be used as a model of leadership. As our group read this book, it was evident that Shackleton was a truly motivated and successful leader as we have come to understand one to be. His ability to successfully lead a team played a significant role in their survival.
Canada’s first ever interest in space exploration came into play during 1959 when the first suborbital sounding rocket was launched from Manitoba.
What do you value most? Different people value different things. Some care about the money, what they have and where they live. Others value what they have accomplished in life. Other people appreciate their family. People who are polite, honorful, and trustworthy deserve the title MVP or, most valuable player. In the book Surviving Antarctica 5 teenagers, Andrew, Polly, Robert, Billy and Grace, risk their lives going to the South Pole for money. This was all put on television and people across the United States watched. Out of the five kids, one gets MVP and an extra $90,000. I believe that Andrew deserves this title because he is selfless, helpful, and sympathetic.
A food desert is a location in which a wide variety of nutrition food is not generally available (Wrigley et al. 261). Food deserts exist in places such as inner cities and isolated rural areas (Morton and Blanchard 1). The purpose of the paper supported by this annotated bibliography is to argue that food deserts do not exist because of discrimination against the poor, but because of forces related to supply and demand. This hypothesis ought to be kept in mind when considering each of the sources (Just and Wansink; Wrigley, Warm and Margetts; Jetter and Cassady; Epstein et al.; Schafft, Jensen and Hinrichs; Bitler and Haider) described in the annotated bibliography.
Have you ever looked up in the sky and wondered if there is life elsewhere in the universe? Have you ever looked at a photograph of Mars and wondered if there really was ever life on it? People have a wide variety of opinions regarding these questions and with good reason. As far back as the broadcast of H. G. Well's novel, "The War of the Worlds", the world has been fascinated with the possibilities of what Mars may hold. Over time, the majority of people have come to realize that there is no way that life can currently be on Mars. Those who are uncertain think there may be microscopic bacteria underground.
In 1914, Ernest Shackleton set of on an exploration across the antarctic. In 1915, his ship, Endurance, became trapped in the ice, and it's crew was stuck.
never heard of? Thanks to space probes these dreams may become a reality sooner than u think. In the past years there have been many space probes launched and even more discoveries made by them. These probes are helping people to better understand our solar system and everything it. They are also helping to make many new discoveries.
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 researchers and support staff for both year-round and austral summer seasons (Dag Jølle n.d.). Most permanent research stations and huts established by various countries around the globe are built on top of barren rock, due to majority of the continent
Antartica is being populated due to global warming and for Antarctica to ensure a stable future the area has decided to have a market economy. A market economy is where the people and businesses are solely guiding the prices for products and services. With a finite amount of goods and resources, a scarcity is possible. With scarcity comes the desire and need to innovate and be more efficient with the resources. With the small amounts of resources that are available to the people of Antarctica, the people need to decide who obtains the scarce resources.
