1.Where was the Russian pesearch vessel leading to ?
Ans: Antarctica.
2.What was the purpose of the visit to Antarctica?
Ans: The purpose of the visit to Antarctica was to understand how real was the threat of global warming and depletion of the ozone layers. Beside this, the author visited Antarctica to undertand the cordilleran folds, ozone and carbon.
3. For how many years did Gondwana thrive?
Ans: It thrived for 500million years.
4.How has Antarctica reminded relatively pristine?
Ans: The impact of climate change is still.
5. How did the author reach Antarctica?
Ans: The author boarded a Russian Research ship called ‘Thje Academik Shokalskiy’. It was headig Antarctica. It is the coldest, driest and windiest continent of the world. His journey began 13.09 degrees north of the Equator in Madras. He had to cross nine time zones, six check points, three bodies of water and at least three ecosphere.
6. What is Gondwana?
Ans: The gondwana was agiant amalgamated southern supercontinet. There the climate was much warmer and a huge variety of flora and fauna existed.The Guwandana thrived for 500 million years. Later the landmass was forced to seperate into countries, shaping the globe much as we know it today.
7. How do geological phenomena help us know about the history of mankind?
Ans: Geological phenomena help us know about the history of human kind. About six hundred and fifty million years ago a giant southern super continent did exist. The climate was much warmer. It had a huge variety of flora and fauna. It thrived for 500 million years. Finally it broke into countries as they exist today.
8. Take care of the small things and the big things will take care of themselves.’ What is the relevence of this statement in the context of the Antarcti environment.
Ans: Antarctica is to the far south point of the globe. It has quite a simple natural ecosytem. It lacks bio-diversity. It is the perfect place to study how little changes in the environment can have big repercussion. The very small one celled photo planktons are the grasses of the sea. They nourish and sustain the entire Southern’s Ocean food chain. They use the sun energy. They assimilate carbon. They synthesise organic compounds. Furhter depletion of the ozone layer will affect the activities of the photo planktons. Consequently whole marine life of animals and birds has gone under changes.
This small thigs have to be taken care of. The author says, ‘if they are taken care of then the big things will fall into places.’
9.Describe the author’s walking experience on the oeean in the Antarctic circle?
Ans: The Russain research ship managed to place herself into a thick stretch of ice. They were instructed to climb down the gang plank and walk on the ocean. Underneath their feet was a metre thick ice pack. And below it was 180 metres living, breathing and salt water.
10. understand the earth’s present, past and future?
Ans: To visit Antarctica is to be a part of Earth’s history. About 650 million years ago there was a giant super continent in the south which was called ‘Gondwana’. India and Antarctiea were parts of the same landmass. Things were quite different then. Humans had not arrived on the Earth. The climate of Antarctica was much warmer. It had a huge variety of flora and fauna. Dinosaurs became extinct. The age of mammal began. The landmass was forced to be seperated into countries as they exist today.
The 90 per cent of the Earth’s total ice volume are stored in Antarctica. There are no trees , buildings and human settlements.
Antarctica also provide a warning fpr the future. If the global warming reducts in constant melting of icebergs, it will bring runious results. The future depletion of the ozone layers will affect sea animals, vegetation and human adversely. A small change in the climate condition of the Antarctica will bring a great change to the condition of the entire earth.
