Textual Question Answer :

Question : How do geological phenomenon help us to know about the history of human kind ?
Ans : 650 million years ago, a giant southern supercontinent Gondwana did exist. The climate was much warmer. It had a huge variety of flora and fauna. Gondwana flourished for 500 million years. Finally it was separated as we know it today. It was the stage where dinosaurs were wiped out and the age of mammals began. Thus the geological phenomenon helps us to know about the history of human kind.

Question : What are the indication for the future of human kind ?
Ans : The rapidly increasing human population and limited resources exert pressure on land. The unlimited burning fossil fuels has only helped in increasing the average global temperature. Melting of ice caps, depletion of ozone layer and global warming are the real and immediate dangers for mankind. They will affect the lines of all the marine animals and the birds of the region.

Question : "The world's geological history is trapped in Antarctica." How is the study of this region useful to us ? OR
Question : What does the writer say about the geological history of Antarctica ?

Ans : The study of the Antarctic region gives us the geological past of human civilization. It gives an idea of the world of 650 million years ago, when the region was not divided into continents and nations. It lasted about 500 million years. But gradually it began to break into countries that we know today. The age of dinosaur was wiped out in this period and mammals came into exist. By visiting Antarctica we can realize that where we have come from and where we are heading towards.

It shows how minor climate changes can change the shape of the region. It gives the reason how the earth's climatic conditions were previously unfavorable for life, and how gradually increasing temperature made the earth a place for sustaining life. All secrets are preserved in the ice layers in the form of carbon records which are half a million years old.

Question : What are Geoff Green's reasons for including high school students in the students on Ice expedition. OR
Question : Describe the narrator's journey to the end of the earth -- the Antarctica region and his experiences during that journey with special emphasis on the success of students on ice programme of Geoff Green.

Ans: Geoff Green has solid reasons why he includes the highschool students in his mission. He realises that our elder people could do nothing to save the world. But the students of the highschool are future of the world. Their proper knowledge on the world will help them to take positive steps towards the safety of the degrading environment. Going to the end of the earth, they can understand, learn and realise the danger of the global warming, ozone layer's degradation and biodiversity problem.

Such expedition will, he expects, increase awareness about the environment of the world. They can realise the real danger by seeing the icecaps retreating and collapsing due to the global warming.

Question : "Take care of the small things and the big things will take care of themselves" What is the relevance of this statement in the content of the Antarctica environment?

Ans: Antarctica has quite a simple ecosystem. It lacks bio-diversity. It is the perfect place to study how little changes in the environment can have big repercussions. The study of the very small one celled phytoplanktons are the grasses of the sea. They nourish and sustain the entire Southern Oceans food chain. They use the sun energy. They assimilate carbon. They synthesise organic compounds. Further depletion of the ozone layer will affect the activities of the phytoplanktons. Consequently whole marine life of animals and birds has gone under changes.

This small things have to be taken care of. If they are taken care of, big things will fall into places.

Question : Why is Antarctica the place to go, to understand the earth's past, present and future?(AHSEC 2014)

Ans: To visit Antarctica is to be a part of earth's past history. About 650 million years ago there was a giant super contient in the south.

It was called Gondwana. India and Antarctica were parts of the same landmass. Things were quite different then.
Human hadn't arrived on the earth. The climate of Antactica was much warmer. It had a huge varity of flora and fauna. Dinosaurs became extinct. The age of mammal began. The landmass was forced into be separated into countries as they exist today.

About 90 percent of the earth's total ice volumes are stored in Antarctica. There are no trees, buildings and human settlements.

Antarctica also provides a warning for the future. If the global warming results in constant melting of icebergs, it will bring ruinous results. The future depletion of the ozone layer will affect sea animals, vegetation and human very adversely. A small change in the climate condition of Antarctica will bring a great change to the condition of the entire earth.

Extra Question Answers :-

Question : How did the narrator/author reach Antarctica ?(AHSEC 2014)
Ans : The narrator boarded a Russian Research ship 'The Akademik Shokalskiy'. After traveling over 100 hours in combination of a car, an aeroplane and a ship, the narrator reached Antarctica. She had to cross nine time zones, six checkpoints and many ecospheres.

Question : What was Gondwana ?
Ans : Gondwana was a giant amalgamated southern supercontinent, the undivided earth, which existed about 650 million years ago. Gondwana was centred roughly around present day Antarctica. It had no human life but only flora and fauna.

Question : Describe two important features of Antarctica as described in the lesson.
Ans : The two important features of Antarctica are -
i) It has a pristine beauty with very little biodiversity.
ii) It holds in its ice-cores half a million year old carbon records trapped in its layers of ice.

Question : Describe the narrator's experience of walking on the water. OR
Question : Describe the walking experience on the ocean in the Antarctica circle.
Ans : All the 52 members of the journey were instructed to got down the gangplank and walk on the ocean. Under their feet was a metre thick ice pack and below the ice was 180 metres of living, breathing and salt water. Seals were sunning on ice.

Question : How has Antarctica remained relatively pristine ?
Ans : Antarctica has always had very little biodiversity and it is the only place in the world which has never sustained a human population. Moreover, it has a pure expense of white serenity. That is why it has always remained pristine.

Question : What is Phytoplankton ?
Ans : The phytoplankton are grasses of the sea. They nourish and sustain the entire Southern Ocean's food chain. They use the sun's energy to assimilate carbon supplying oxygen.

Question : What was the first emotion of the narrator on facing Antarctica?
Ans: On facing Antarctica she got great relief. Its vastness and immense white landscape dazzled her eyes. Its isolation from rest of the world created a sense of wonder and mystery.
