where do the sentences go in the passage
P.4-activity5
Since then another 32 countries have signed the treaty.
In 1961, a treaty signed by 12 countries, including Britain, France, and the USA made Antarctica the world’s biggest nature reserve.
The aim of the treaty is to prevent the commercial and military use of the continent.
Para 5.
Over the next 15 years a number of unsuccessful journeys to the pole were made by explorers such as Ernest Shackleton and Robert Scott.
Then in 1895, a Norwegian called Carstens Borchgrevink became the first man to set foot on the Antarctic mainland. The race to the pole had begun.
It was finally reached on 11th December, 1911 by the Norwegian Roald Amundsen.
Para 4.
If the ice melted, the sea level would rise by about 60 metres.
Antarctica holds 90% of the world’s ice, and most of its fresh water (70%) is in a frozen state, of course. 98% of the surface is covered permanently in the ice cap. On average it is two kilometers thick, but in some places it reaches a depth of five kilometers.
Strong winds driven by gravity blow from the pole to the coastline, while other winds blow round the coast. It is difficult to imagine a more inhospitable place.
Para 1.
Some have come from the Moon and Mars.
Antarctic rocks are also very important for research. Most of them are meteorites from outer space.
One rock, known as the “Alien” rock, may contain evidence of extra-terrestrial life.
Para 3.
There are different types of penguins, flying birds, seals, and whales.
But the long Antarctic winter night, which lasts for 182 days (the longest period of continuous darkness on earth), as well as the extreme cold and lack of rainfall, means that few types of plants can survive there.
Most animals survive thanks to their fat,which protects them from the cold.
