Antarctica occupying a total area of about 14 million square kilometers, of which the mainland area of 12.39 million square kilometers and islands area of about 7.6 million square kilometers, 2.47 million meters long coastline. Approximately 1.582 million square kilometers of the Antarctica has a snow cover. Antarctica occupies 10% of the total land area of the earth, and its size is equivalent to one and a half of China.

Because of a high altitude, thin air, coupled with the snow and ice on the surface of the solar reflection, has been the result that the Antarctica becoming the coldest areas in the world, with an average temperature 20 degrees lowers than the Arctic's temperature.
There is a common phenomenon with 12 or more tropical storms (typhoon) in the Antarctica and it is by far the most frequent turmoil, with wind speed above 100km per hour. The France “Dierweier” observation team has detected the wind speed with 100m per second, a wind speed of 12 typhoons three times, and its destructive power is equivalent to 10 times of 12 typhoons. Therefore, the Antarctic is renowned for a characteristic of “very windy.”
Luoerde Amundsen (Roald Amundsen) is the first explorer who reached Antarctica on December 14, 1911. A month later, Robert Scott (Robert Falcon Scott) arrived at the Antarctica. However, Scott and his four companions were dying of hunger due to extremely cold weather in the Antarctica.
Exploring the Beauty of Antarctica
Migration process is usually a tiring and hard journey for the penguins to venture. When they hardly bear on hardships while walking over the time, they will use their fat belly to crawl around the ice or snow.
These emperor penguins have gigantic heads. They are the giant penguins in the world. In general, their height is 90cm, but they can achieve as high as 120cm in height. Their maximum weight is 34kg. These penguins are monogamy but not polygamy, and thus the family structure of them is one wife and one husband. After laying the eggs, mother penguin will hand over the eggs to father penguin. Then the mother penguin goes out in search for foods, while the father penguin incubates the eggs. Every year in March, these penguins will leave the ocean and migrate to different places that they find free from natural enemies to produce offspring. Almost all the penguins from these species will have a mass migration to leave the sea every year. Their two feet walk in a slow pace as tough a baby starts walking to explore their challenging and attractive journeys.
These penguins have small black feathers from the side of the ear pass through their chins and to the other side of the ear. Sometimes, people call them “police officer's penguin.” Their height can extend from 43 to 53cm and weighing 4kg. These penguins are very aggressive, as they prefer to fight. Their reproductive season is in every winter. Mother penguin produces two eggs each time, while the father penguin incubates the eggs. Both father and mother penguins will take turn to take care of their baby penguin.
Young penguins has strict custody and well care from both of their parents, nevertheless, young penguins have to bear on the harsh environmental condition in the Antarctic coupling with the threat from the predators. Therefore, the survival rate for them is relatively low with their low birth rate of 20% to 30%.
Penguins are renowned for loving their nests the most. Sometimes, they steal the neighbor's eggs by conquering other penguins' nests. They monopolize the custody by taking care of other baby penguins that they succeed to steal. Thus, penguins refuse to leave their children even a second as they fear of losing their children. When mother penguin is out in search for foods, father penguin will take strict supervision to their children. Similarly, when father penguin is out for “business affairs,” mother penguin will take over the responsibility to look after their children.
Young penguins stand at the feet of their parents, while adult penguins will use their abdominal features to let their children stay warm. On the whitish and ice-covered land, penguins nest and feed their children. Both male and female penguins will take turn to hatch the eggs. The hatching process takes approximately one to two months.
In order to survive their lives, penguins have to adapt themselves to an extreme weather in the Antarctic. Therefore, they always walk in a crowd close to other penguins with their back facing out. Their ancestors have taught them how to walk against the cold and strong winds with the speed of 160km per hour. The penguins that walk out of the group will always rotate to the middle of the group to get warmth. The empty place left by them will be filling by the penguins in the middle group. They will always take turn to get warmth. The spirit of unity ensures them to store the energy in their bodies to continue to survive at the harsh environmental condition in the Antarctic island.
