Extract Based Questions:

A. You lose all earthly sense of perspective and time here. The visual scale ranges from the microscopic to the mighty: midges and mites to blue whales and icebergs as big as countries (the largest recorded was the size of Belgium). Days go on and on and on in surreal 24-hour austral summer light, and a ubiquitous silence, interrupted only by the occasional avalanche or calving ice sheet, consecrates the place. It’s an immersion that will force you to place yourself in the context of the earth’s geological history. And for humans, the prognosis isn’t good.

Question. Select the option that correctly fits the category of ‘microscopic to the mighty’ out of the ones given below.
1. trace of a skin cell: trace of a bird’s egg

SHORT-ANSWER TYPE QUESTIONS :

Question. What has been the result of rapid increase of human populations ?
Answer : The rapid increase of human populations has resulted in many problems. Natural resources have become limited. Thus a battle with other species has started. Limitless burning of fossil fuels has created a blanket of carbon dioxide around the world. It has increased the average global temperature.

Question. How can you say that the ‘Students on Ice’ programme has been successful ?
Answer : The aim of this programme was to make the younger generation aware of the dangers of global warming. Those who visited Antarctica under this programme, saw for themselves glaciers retreating and ice shelves collapsing. Thus they realised that the threat of global warming was very real.

Question. For how long did Gondwana thrive, and when did it separate into various countries ?
Answer : Gondwana thrived for about 500 million years. It separated into various countries around the time when the dinosaurs disappeared from the earth. It was when mammals had begun to appear.

Question. Why is a visit to Antarctica important to realise the effect of global warming ? 
Answer : A visit to Antarctica can show us the reality of receding glaciers and collapsing ice shelves. They can give us an indication of the horrible future. They can tell us how real the threat of global warming is.

Question. In a short span of twelve thousand years, man has managed to create a ruckus on this earth. How ?
Answer : Man has dominated nature everywhere. He has dominated each and every corner of land and sea. He has explored all the mineral wealth of the earth. Thus it is quite appropriate to say that man has managed to create a ruckus on this earth.

Question. What is Drake Passage ? How was it formed ?
Answer : It is a 1000-km-wide strait that connects the southern Atlantic and Pacific oceans. It is a cold circumpolar current that goes round Antarctica. It was formed when India and South America separated from Gondwana and drifted northward.

Question. What is unique and typical about Antarctica ?
Answer : Antarctica is the only place in the world which never had any human population. It remains pristine in this respect. Secondly, it holds half-million-year-old carbon records. They lie trapped in its layers of ice.

Question. How were the Himalayas formed ?
Answer : About a million years ago, India used to be a part of the southern supercontinent — Gondwana. Somehow it was pushed northward. It jammed against Asia. Its crust got buckled and thus the Himalayas were formed.

Question. How did the author feel when she first set foot on Antarctic continent ?
Or
How did Antarctica amaze the writer when she first saw it ? 
Answer : The writer’s first emotion was that of relief and amazement. It was relief at the sight of Antarctica’s expansive white landscape and uninterrupted blue horizon. Then she was amazed at its immensity and isolation. She wondered how there could have been a time when India and Antarctica were part of the same landmass.

Question. What was the objective of the ‘Students on Ice’ programme ? 
Answer : Its aim was to take high school students to the ends of the world. Thus they could get inspiring educational opportunities. Through their experiences, they could develop a new understanding and respect for their planet. Thus as future policy-makers, they could help to save the planet from the present dangers.

Question. What does the author say about the life of human civilizations ?
Answer : Human civilizations have been there for about 12,000 years. But on the geological clock, this time comes to a few seconds only. However, in this short time, man has created much ruckus. He has dominated nature.

Question. How is Antarctica a crucial element in the debate on climate change ?
Answer : The climate of the globe is changing gradually. And if this continues, it is finally Antarctica that is going to determine the future of the earth. The polar ice caps will start melting and there will be floods everywhere. Thus Antarctica is a crucial element in the debate on climate change.

Question. What is one of the most hotly contested environmental debates of our time and why ?
Answer : Climate change is one of the most hotly contested topics. The climate of our globe is changing gradually. It is growing warmer and warmer. As a result, the polar ice caps will start melting. The danger of floods will thus increase.

Question. What information does the author give about Gondwana ?
Answer : Six hundred and fifty million years ago, Gondwana was the southern supercontinent. It centred roughly around present-day Antarctica. Humans had not yet arrived on the global scene. The climate was much warmer. There was a huge variety of flora and fauna.

Question. How do geological phenomena help us to know about the history of humankind ? 
Answer : Geological phenomena can help us to know where we have come from and where we are possibly heading. They tell us how the different continents were formed. Similarly, the melting of the polar caps can tell us where possibly we are heading.

Question. What are the indications for the future of humankind ? 
Answer : There are ominous indications for the future of humankind. The average global temperature is slowly but surely increasing. The threat of global warming is very real. These grave indications don’t augur well for the future of humankind.

Question. What do you know about ‘phytoplankton’ ?
Answer : They are single-celled plants. They are grasses of the southern ocean. Through the process of photosynthesis, they supply food and oxygen for all the marine animals and birds of the region. But global warming can affect the activities of these plants and the life of all creatures depending on them.

Question. How can a visit to Antarctica be an enlightening experience ? 
Answer : A visit to Antarctica can tell us how our globe took its present-day shape. It can tell us how there was a time when India and South America used to be a part of the southern continent. Thus a visit to Antarctica can be an enlightening experience.

Question. How does Tishani Doshi describe her journey from Madras to the world’s coldest, driest and windiest continent ?
Answer : Doshi says that the journey began 13.09 degrees north of the Equator in Madras. It involved crossing nine time zones, six checkpoints, three bodies of water and at least three ecospheres. She had to travel over 100 hours in combination of car, aeroplane and ship.

Question. Why is Antarctica and its understanding important for the survival of the world ?
Answer : The study of Antarctica tells us of the effect of global warming on the world. Due to global warming, glaciers are receding. If this continues, the polar ice caps will start melting and there will be floods everywhere. This will bring about the end of the world. Thus Antarctica and its understanding is important for the survival of the world.

LONG-ANSWER TYPE QUESTIONS :

Question. What are phytoplankton ? How are they important to our ecosystem ?
Answer : Phytoplankton are microscopic grasses of the sea. They form the food chain for the entire Southern Ocean’s marine life. These single-celled plants use the sun’s energy to assimilate carbon dioxide through the wonderful process called photosynthesis. Scientists warn us that a further depletion in the ozone layer will affect the activities of phytoplankton. The harmful rays of the sun will enter the earth’s atmosphere and harm these single-celled plants. Their destruction will, in turn, affect the lives of all marine animals and birds of the region. Thus the phytoplankton grasses are very important to our ecosystem. By assimilating the atmospheric carbon dioxide, they serve a very useful purpose. Without them, the carbon dioxide level would increase to a harmful extent for all living things on the earth. Also a big source of food for marine life will disappear from the seas.

Question. ‘The world’s geological history is trapped in Antarctica.’ How is the study of the region useful to us ? 
Or
How can we say that Antarctica is the best place to study and understand about Earth’s present, past and future ? Answer with reference to ‘Journey to the End of the Earth’.
Answer : The study of Antarctica can tell us how our globe took its present-day shape. It can tell us how there was a time when India and South America used to be a part of the southern supercontinent — Gondwana. Then about a million years ago, India pushed northward and jammed against Asia. Its crust buckled and formed the Himalayas. South America drifted off to join North America. The study of Antarctica also tells us that it is the only place in the world that never had any human populations. It remains relatively pristine in this respect. It has in its ice cores half-million-year-old carbon records. They are all trapped in its layers of ice. Thus if we want to study and examine the Earth’s past, present and future, Antarctica is the place to go to. Its receding glaciers and collapsing ice shelves will tell us how real the threat of global warming is. Thus the study of the region can be very useful to us. It can help us to learn from our mistakes.

Question. ‘Take care of small things and the big things will take care of themselves.’ What is the relevance of this statement in the context of the Antarctic environment ?
Answer : The Antarctic environment has been affected by global warming. It is clear from receding glaciers and collapsing ice shelves. But the danger of global warming starts from what appears to be a small thing. It starts from the burning of fossil fuels. No harm can come if we make a wise and judicious use of these fuels. But we have started using them carelessly. Their overuse has disturbed the global carbon cycle. The ozone layer has been affected. The very life on this globe has come in the danger of extinction. In other words, the neglect of a small thing has resulted in a terrible danger. This big danger can be averted only if we become careful about small things like the burning of fossil fuels and fast increase of population. The writer gives the example of phytoplankton which are single-celled plants. They are grasses of the sea. These tiny plants form the food chain for all the marine animals and birds of the region. Thus the writer shows how big things will take care of themselves if we take care of small things. If we take care of phytoplankton, all marine life of the Southern Ocean will take care of itself.

Question. What are Geoff Green’s reasons for including high school students in the ‘Students on Ice’ expedition ?
Answer : Geoff Green looks upon students as important and responsible members of our future generation. They are our future policy-makers. They have the ability to absorb, learn and act. That was why he included high school students in his expedition. By their visit to Antarctica, they could see for themselves how real the danger of global warming is. Receding glaciers and collapsing ice shelves could tell them how the danger of floods was increasing day by day. Thus they could develop a new understanding and respect for their planet. And when they grow up, they will take steps to stop the harms that are being done to the earth. They will take steps to fight such problems as the rapid increase of human populations and unmitigated burning of fossil fuels. They will take steps to ensure that life continues to exist on this planet. It was for these educational reasons that Geoff Green included high school students in the ‘Students on Ice’ expedition.

EXTRA QUESTIONS :

Question. What are the indications for the future of mankind ?
Answer : The indications for the future of mankind are not good. Human civilization is just 12,000 years old. It comes to only a few seconds on the geological clock. And in this short span of life, we have dominated nature with our villages, towns, cities and megacities. Human population has increased so much that it has come to be called as ‘population explosion’. We have gravely depleted our resources of nature. We have destroyed our forests and many species of wildlife have become extinct. The excessive burning of fossil fuels has created a blanket of carbon dioxide around the earth. The average global temperature is slowly but surely increasing. The threat of global warming is very real. Climate change has become one of the most hotly debated environmental debates of our time. These grave indications don’t augur well for the future of mankind. They may or may not bring about the end of the world. But they are not good.

Question. ‘Take care of small things and the big things will take care of themselves.’ What is the relevance of this statement in the context of the Antarctic environment ?
Answer : The Antarctic environment has been affected by global warming. It is clear from receding glaciers and collapsing ice shelves. But the danger of global warming starts from what appears to be a small thing. It starts from the burning of fossil fuels. No harm can come if we make a wise and judicious use of these fuels. But we have started using them carelessly. Their overuse has disturbed the global carbon cycle. The ozone layer has been affected. The very life on this globe has come in the danger of extinction. In other words, the neglect of small things has resulted in a terrible danger. This big danger can be averted only if we become careful about small things like the burning of fossil fuels and fast increase of population.

Question. ‘The world’s geological history is trapped in Antarctica.’ How is the study of the region useful to us ?
Answer : The study of Antarctica can tell us how our globe took its present-day shape. It can tell us how there was a time when India and South America used to be a part of the southern supercontinent — Gondwana. Then, about a million years ago, India pushed northward and jammed against Asia forming the Himalayas. South America drifted off to join North America. The study of Antarctica also tells us that it is the only place in the world that never had any human population. It remains relatively pristine in this respect. It has in its ice cores half-million-year-old carbon records. They are all trapped in its layers of ice. Thus the study of this region can tell us about the Earth’s past. It can also tell us about its present and future. Its receding glaciers and collapsing ice shelves tell us how real the threat of global warming is. Thus the study of the region can help us to learn from our mistakes.

Question. How do geological phenomena help us to know about the history of mankind ?
Answer : Geological phenomena can help us to know where we have come from and where we are possibly heading. For example, geological phenomena tell us how India and South America formed a part of the southern supercontinent — Gondwana. Then due to some geological changes, India pushed northwards, jamming against Asia and forming the Himalayas. South America drifted off to join North America. Similarly, the melting of the polar ice caps can tell us where possibly we are heading.

Question. Why is Antarctica the place to go to, to understand the earth’s present, past and future ?
Answer : Antarctica is really the place to go to if we want to understand the earth’s present, past and future. It can tell us how our globe took its present-day shape. It can tell us how there was a time when India and South America used to be a part of the southern supercontinent — Gondwana. Then, about a million years ago, India pushed northward and jammed against Asia forming the Himalayas. South America drifted off to join North America. The study of Antarctica also tells us that it is the only place in the world that never had any human population. It remains relatively pristine in this respect. It has in its ice cores half-million-year-old carbon records. Thus Antarctica tells us of the present state also. It can tell us the Earth’s past. Its receding glaciers and collapsing ice shelves can give us an indication of the future also. They can tell us how real the threat of global warming is. Thus Antarctica is really the place to go to if we want to understand the earth’s present, past and future.

Introduction
 
In ‘Journey to the End of the Earth’ Tishani Doshi describes the journey to the coldest, driest and windiest continent in the world, Antarctica. The world’s geological history is trapped in Antarctica. Geoff Green’s ‘Students on Ice’ programme aims at taking high school students to the ends of the world. Doshi thinks that Antarctica is the place to go and understand the earth’s present, past and future.
 
Summary
 
Biginning of Journey- The narrator boarded a Russian research ship-The 'Akademik Shokalskiy'. It was heading towards the coldest, driest and the windiest continent in the world, Antarctica. His journey began 13.09 degrees north of the Equator in Madras (Chennai). He crossed nine time zones, six checkpoints, three bodies of water and at least three ecospheres. He travelled over 100 hours in car, aeroplane and ship to reach there.
Southern Supercontinent (Gondwana)- Six hundred and fifty million years ago a giant southern supercontinent Gondwana did indeed exist. It centered roughly around present-day Antarctica. Human beings hadn't arrived on the global scene. The climate at that time was much warmer. It supported a huge variety of flora and fauna. When the dinosaurs became totally extinct and the age of mammals began, the landmass was forced to separate into countries as they exist today.
 
Study of Antarctica-The purpose of the visit was to know more about Antarctica. It is to understand the significance of Cordilleran folds and pre-Cambrian granite shields; ozone and carbon; evolution and extinction. Ninety per cent of the earth's total ice volumes are stored in Antarctica. Icebergs are as big as countries. Days go on and on in 24-hour austral summer light. Human Impact- The most hotly contested debate of our time is whether West Antarctica Ice sheet will melt entirely or not. If we want to study the earth's past, present and future, Antarctica is the place to go. Antarctica has a simple eco-system and lack of biodiversity. It is the perfect place to study how little changes in the environment can have big repercussions (results). Scientists warn that a further depletion of the ozone layer will affect the lives of the sea-animals and birds of the region. It will also affect the global carbon cycle. The burning of fossil fuels has polluted the atmosphere. It has created a blanket of carbon dioxide around the world. It is increasing the global temperature which is visible at Antarctica when we see ice bergs melting away. It shows how minor changes in the atmosphere can cause huge effect. If the global temperature keeps on increasing the human race may be in peril. ‘Students on ice’ is a programme which provides the students an ample opportunity to understand how global temperature can be a big threat to human existence. It inculcates a new understanding in them.Geoff Green thinks that high school students are the future policy makers. They can help in saving the earth from ecological dangers and the effects of global warming.
 
Effect of Climatic Change- The author gives us an example to show how small changes in the atmosphere can be threatening. The microscopic phytoplanktons are single celled plants. They nourish the entire Southern Ocean’s food chain. They use the sun’s energy to assimilate carbon and supply oxygen. Any further depletion in the ozone layer may affect this functioning and indirectly affect the lives of all marine animals.
 
Walk on the Ocean-It was the most thrilling experience of the visit. They climbed down the gangplank and walked on the ocean. They were 52 persons. They were walking on a meter-thick ice-pack. Under the ice pack there was 180 meters of living, breathing, salt water. Seals were enjoying themselves in the sun on ice. The narrator was wondering about the beauty of the place. He wished it would not become a warm place as it used to be millions of years ago. If it happens, the results can be ruinous.
 
Short answer Questions :
 
Question. Why did Geoff Green decide to take high school students to Antarctica?
Answer : Geoff Green didn’t find any good in taking curious celebrities to Antarctica. He thought of taking high school students, as their curious minds would easily understand the seriousness of the threat that poses the earth. By visiting Antarctica and they would do their bit to save the planet from further deterioration.
 
Question. Why is Students on Ice Program a success?
Answer : When one stands in the midst of the calving ice-sheets and retreating glaciers and melting icebergs, he realizes that the threats to the earth are real. It is different from talking about Antarctica from the comfort zones of our warm countries. Therefore being in Antarctica is a shocking realization.
 
Question. How is Antarctica significant in climatic debates?
Answer : Antarctica is a continent that has a landmass with miles deep ice, layers over layers. In each of those layers lie millions of years old carbon records of the organisms that existed since the beginning of the earth. While pondering over the issue of the future of the earth, these carbon records will shed light on the past and enable the scientist to co-relate the past, present and future.
 
Question. How do geological phenomena help us to know about the history of humankind?
Answer : Geological phenomena certainly help us to know about the history of humankind. A giant southern supercontinent- Gondwana did exist 650 million years ago. The climate was much warmer. It had a huge variety of flora and fauna. Gondwana thrived for 500 million years. Finally, it broke to separate countries as they exist today. It was the stage when dinosaurs were wiped out and the age of mammals started.
 
Question. The world’s geological history is trapped in Antarctica. How is the study of this region useful to us? 
Answer : The study of Antarctica shows that India and Antarctica were part of a supercontinent named Gondwana. This supercontinent existed 650 million years ago. The climate of Gondwana was much warmer. It fostered a huge variety of flora and fauna. Then about 150 million years ago, dinosaurs were wiped out. The age of mammals started. Gondwana was forced to separate into countries. The globe was shaped much as we know it today. A cold circumpolar current was
created. It made Antarctica frigid. Thus, we can say that the world’s geological history is really trapped in Antarctica.
 
 
Long Answer Questions :
 
Question. ‘Take care of small things and big things will take care of themselves.’ What is the relevance of this statement in the context of the Antarctica’s environment? Answer in 120-150 words.
Answer : Antarctica has a simple ecosystem and lacks biodiversity. It is the best place to study how little changes in the environment can have big consequences.
The author gives the example of very small single celled plants called phytoplankton which nourish and sustain the entire southern ocean‘s food chain. The phytoplankton uses the energy to absorb carbon and also synthesize various organic compounds through photosynthesis. Scientists have forewarned that if ozone layer depletes any further it will have a direct impact on the activities of the phytoplankton. This will lead to a chain reaction adversely affecting the lives of marine animals and birds of the region which will further result in the disturbance global carbon cycle.
So, it is expected of man to pay special attention to tiny forms of animal and plant life and prevent the depletion of ozone layer by reducing carbon dioxide emissions. If we take care of small things big things will automatically fall into place.
 

GIST OF THE LESSON

• The writer Tishani Doshi was part of a programme called 'Students on Ice' and was taken to Antarctica. She shares her experiences and impressions.
• The aim of the expedition was to take high school children to Antarctica, thereby providing them with a unique educational opportunity to see first hand the effect of human activities on environment so that these youngsters, when the time comes to act, will take correct decisions regarding conservation of the environment.
• Antarctica is the right place to study about the changes in the environment and its impact on humanity as a whole.
• Antarctica holds the secrets of how earth came to be in its present form. It gives us an insight into how the present landforms came into existence, why certain animal species became extinct.
• Complete absence of human beings has preserved the carbon records intact.
• Lack of bio-diversity in Antarctica makes it possible to study the effect of small changes in the environment on the animal life and environment.
• It was a humbling experience for the author and she feel that we need to address environmental issues immediately, if mankind is to survive.

SHORT ANSWER QUESTIONS

Question. What were Geoff Green's reasons for including high school students in the 'Students on Ice' expedition?
Answer: Children are more receptive and ready to absorb, learn and most importantly act. Unlike the elderly people who are at the end of their productive life, children can giveback to society substantially and practice what they learn and experience. Most importantly, they can take correct decisions and act when the time comes and save the environment.

Question. How does the writer realize that the threat of global warming is very real?
Answer: The writer visits Antarctica and sees for herself the glaciers retreating and ice shelves collapsing. She sees with naked eyes the effect on the food chain when a singled celled phytoplankton is removed from food chain. That's when she realizes that threat of global warming is real.

Question. What revelation did the author have on her visit to Antarctica?
Answer: The writer on her visit to Antarctica noticed the beauty of balance in play on our planet and realizes that everything in the world is inter-connected.

Question. What is phytoplankton? What is their importance?
Answer: Phytoplanktons, the grasses of the sea are single celled organisms living in the southern ocean.
They nourish and sustain the entire ocean's food chain , being e the first link in the food chain of the ocean. Using sun's energy , they assimilate carbon and synthesize organic compounds.
The diminishing number of this organism due to the depletion of ozone layer affects other organisms of the ocean , finally leading to the extinction of life on earth..

LONG ANSWER QUESTIONS

Question. 'Take care of small things and the big things will take care of themselves-. What is the relevance of this statement in context of the Antarctic Environment?
Answer: Suggested Value Points: The Statement- greatly relevant in the context of Antarctic Environment - only place not strained by man - remains pristine - carbon records preserved in its folds - simple eco system - lack of bio-diversity - perfect place to study how small changes can have big repercussions - example of phytoplankton - how it uses sun's energy to synthesize food - process of photosynthesis - Depletion of ozone layer effects phytoplankton - life of small marine animals - in turn the food of large animals - Global warming effect all animals and plants on earth - evident in Antarctica.
