"The freezing land: The Antarctic"

The Antarctic is the fourth largest continent in the world, but as it is situated almost entirely within the Antarctic Circle it is not inhabited. During the winter it doubles in size by the large amount of sea ice that forms on its periphery. Over 95% of Antarctica is covered by ice, which contains about 90% of all the fresh water in the world.

Economic exploitation of Antarctica is very scarce and is only limited to activities such as fishing and hunting. There are important mineral deposits (uranium, gold, coal, copper, oil) but they are not very economical. Also, an international agreement was signed for not to extract any mineral from Antarctica in the following 50 years.

Freezing weather, called "tundra", prevails in almost the entire surface, where the average temperature of the warmest month does not exceed 0 ° C.

These low temperatures are due to its location in the polar zone and to his great average height and low solar radiation received. Moreover, between 80% and 90% of the radiation received is reflected by the ice, avoiding warming the surface.

In the Antarctic  have also been recorded the strongest winds of the earth's surface: 327 km / h, in July 1972, in the French scientific station Dumont d'Urville.

The Antarctic is, in most of its length, in terms of humidity, paradoxically, the driest place on Earth. This is consequence of the freezing temperatures often below 0 ° Celsius that it crystallizes  water and air and make them extremely cold, barely retains moisture.

Among the animals that live in Antarctica we found whales, seals, sea lions and penguins, crabs, mollusks, some flying birds like seagulls and albatrosses, among others.

Hello everyone! My name is Nicolás. I am an 19-year-old chilean boy, born and raised in Villarrica. I consider myself as a cheerful and friendly person, so I really like meeting new people.

    Dear Javier, the planet Earth has so much beauty and it's very good that you make effort to investigate more and more.
    In the English language, the verb doesn't stand on its own, the verb must be accompanied by subject (the noun or the pronoun). In this case, "but as it is situated almost entirely within the Antarctic Circle, IT is not inhabited." & "During the winter IT doubles in size.."
    The economic exploitation IS limited to... (a singular noun must be followed by a singular verb).
    "Also there are signed an international agreement for don't extract any mineral in Antarctica for 50 years." --> The construction of this sentence should be changed and here is the explanation: And English sentence always has the form of "subject-verb-object" that means, "an international agreement was signed for not to extract any mineral from Antarctica in the following 50 yrs/in the next 50 yrs."
    The same happens with this sentence:On almost the entire surface of the antarctic prevails a frozen weather ---> "Freezing weather prevails in almost the entire..."
    ...and this sentence: "In the Antarctic the strongest winds have ALSO been recorded.." (in present perfect "also" is put between the two verbs.
    "Freezing" is the adjective, so there is freezing weather/freezing temperatures, etc.
    Regards!!
