    Journey to the end of the Earth Important Questions CBSE Class 12 English

    1. Answer each of the following questions in about 30-40 words:

    Question 1.

    How do geological phenomena help us to 1 know about the history of mankind? (2000; 2009 Delhi)

    Answer:

    It is geological phenomena that help us to know about the history of mankind. Geologists say about 650 million years ago a giant ‘amalgamated’ super continent, Gondwana existed in the South. At that time India and Antarctica were parts of the same landmass. Gondwana had a warm climate and a huge variety of flora and fauna. This supercontinent survived for 500 years till the age of mammals got underway.

    Question 2.

    What kind of indications do we get while visiting Antarctica to save Earth? (2004 Delhi)

    Answer:

    Tishani Doshi’s entire experience of visiting Antarctica was nothing short of a revelation. It made her wonder about the “beauty of balance in play on our planet”. She hopes the new generation will understand their planet better and save it from annihilation. The planet’s ecosystem and its balance that took millions of years to form can be soon destroyed. Scientists warn that a further depletion in the ozone layer will affect the activities of the phytoplankton. The lives of the marine animals and birds of the region will be affected. But the school students’ visit to the Antarctica may make human beings handle their planet in a better way.

    Question 3.

    How can a visit to the Antarctica be an enlightening experience? (2008 Outside Delhi; All Comptt. Delhi)

    Answer:

    By visiting the Antarctica we can understand the earth’s past, present and future. A visit there can teach the next generation to understand and value our planet. Antarctica also holds within its ice-cores half-million-years old carbon records which will help us to study climatic changes by global warming.

    Question 4.

    Why is a visit to Antarctica important to realise the effect of global warming? (2008 Outside Delhi)

    Answer:

    Antarctica is the perfect place to study the effects that global warming is causing. It is here that one can see the effect of melting glaciers and collapsing ice-shelves and how this is likely to raise the water levels in the sea and the ocean, as a result of which many low lying regions will be submerged under water.

    Question 5.

    How is Antarctica a crucial element in the debate on climate change? (2008 Outside Delhi; 2013 Comptt. Outside Delhi)

    Answer:

    Antarctica is a crucial element in the debate on climate change because it is the only place in the world which has never sustained a human population and thus remains relatively pristine. Moreover, it holds in its ice-caves half-million- year old carbon records trapped in its layers of ice. The world’s climate is changing fast and is at present one of the most hotly debated issues. Antarctica is the ideal place to study the effect of these environmental changes as it has a very simple ecosystem and lacks biodiversity. If global warming makes Antarctica warmer, it will have disastrous consequences elsewhere.

    Question 6.

    What was the objective of the ‘Students on Ice Programme’? (2009 Delhi; 2011 Comptt. Outside Delhi)

    Answer:

    The objective of the ‘Students on Ice’ programme was to take High School students to the limits of the world and provide them not only with inspiring opportunities in education but also enable them to understand and respect our planet. The idea was to provide them a life-changing experience at an age when they are ready to absorb, learn and most importantly act. According to Geoff Green, the High School students are the future policy makers and through this programme they would save this planet from ecological hazards and the harmful effects of global warming.

    Question 7.

    Why is Antarctica and its understanding important for the survival of the world? (2009 Outside Delhi)

    Answer:

    Antarctica and its understanding is important for the survival of the world because it helps us to know that the southern supercontinent of Gondwana existed and centered around the present-day Antarctica. Human beings had not come on the global scene but a huge variety of flora and fauna was present in the supercontinent. It was after 500 million years that the landmass was forced to separate into countries that exist today. Antarctica’s ice-cores hold over half-million-year-old carbon records which are crucial for the study of the Earth’s past, present and future.

    Question 8.

    What are the indications for the future of humankind? (2009 Outside Delhi)

    Answer:

    A fast and steady rise in human population in proportion to the limited natural resources is exerting pressure on land. Forests are being cut and fossil fuels are being burnt and these factors are increasing the global temperature. Melting of glaciers, depletion of ozone layer and global warming are endangering man’s existence on earth. This is bound to adversely affect marine life, birds and mankind.

    Question 9.

    How did the Antarctica amaze the writer when he first saw it? (2010 Delhi)

    Answer:

    When the writer first saw Antarctica he was amazed by its vastness and immense white landscape. It was an endless blue horizon and the fact that it was isolated from the rest of the world created an added sense of wonder and mystery about the continent.

    Read and Find Out

    1. How do geological phenomena help us to know about the history of humankind?

    Answer The geological phenomenon of separating various continents and water bodies from one compact landmass tells us about the age of existence of human race on the earth. Six hundred and fifty million years ago, no human race existed on the earth because the environment was not favourable. After the time when the dinosaurs were wiped out, the Mammals started existing and after the separation of landmass, the human race started flourishing on the earth.

    1. What are the indications for the future of humankind?

    Answer The future of the humankind can get in danger if the emission of carbon- dioxide and other poisonous gases go on in the same manner. These gases deplete the ozone layer and allow the ultra-violet rays of the sun to enter the earth’s environment. This causes the rise in temperature of the earth and giving rise to the phenomenon called global warming. Increased temperature can melt the ice of the Antarctica, and cause other environmental problems, thus jeopardizing the future of human kind.

    Reading with Insight

    1. ‘The world’s geological history is trapped in Antarctica.’ How is the study of this region useful to us?

    Answer

    The study of this region of Antarctica gives us insight into the world’s geological history. It gives an idea, how the earth was like, before it drifted into continents and countries. It shows how slight changes in the climate can change the shape of the region. It gives the explanation how the climatic conditions of the earth were not favourable for life before and how slowly rising temperature made earth a place to sustain life. All secrets are embedded in the layers of ice in the form of half million year old carbon records.

    2. What are Geoff Green’s reasons for including high school students in the Students on Ice expedition?

    Answer Geoff Green took the high school students to one end of the world, to provide them the opportunity to develop the respect and understanding for the earth. He wanted to make the future policy-makers to experience how difficult it would have been for the earth to sustain life by rising its temperature. He wanted them to understand that any interference in nature can cause drastic mishappenings in the future when the students see the ice shelves melting and collapsing, they can estimate the kind of environmental troubles ahead in their future.

    3. ‘Take care of the 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 This statement has great relevance in the context of the Antarctic environment. A small change in the environment can give rise to drastic developments. Antarctica has a small biodiversity. The example of small grass called phytoplankton can be studied in this context. These microscopic grasses undergo the process of photosynthesis and serve as food for number of marine birds and animals. The author says if there is further depletion of the ozone layer, it will affect the phytoplanktons and the carbon cycle on the globe. This whole process can jeopardize the existence of all the marine birds and animals. So if we take care that processes carried over by these small grasses are carried out properly, the bigger animals and birds will fall into the place on their own.

    4. Why is Antarctica the place to go to, to understand the earth’s present, past and future?

    Answer Antarctica gives us an idea, how the earth would have been like millions of years ago and how it got divided into various earth masses. The melting and colliding ice masses also give us an insight into how our future is going to be, if we continue with interference in the working of the nature. Moreover, Antarctica holds into the depths of its ice half-million year old carbon records, which are helpful in understanding the past, present and future of the earth. Therefore, Antarctica is the place which reveals our past, shows our present and visualizes our future.Go Back To Chapters

    Journey to the end of the Earth Introduction

    The lesson revolves around the world’s most preserved place, Antarctica. Not many people have been there but out of the few that have, Tishani Doshi is one of them. A south Indian person who went on an expedition with a group of teenagers affiliated with ‘Students on Ice’ programme takes young minds to different ends of the world. Thus, it gives an insight into how Antarctica is the place you should visit to have a glimpse of the past, present and future in its realist form.

    Journey to the end of the Earth Summary

    For a south Indian man travelling to Antarctica from Madras, it takes nine time zones, six checkpoints, three water bodies and just as many ecospheres to reach there. Tishani Doshi travelled to the Southern end of the Earth along with an expedition group named ‘Students on Ice’ that provides an opportunity to the young minds to sensitise towards the realistic version of climatic changes happening in the world. According to the founder of the organisation, we are the young versions of future policymakers who can turn the situation around. Antarctica is one of the coldest, driest and windiest continents in the world.

    As far as the eyes can see, it is completely white and its uninterrupted blue horizon gives immense relief. It is shocking to believe that India and Antarctica were part of the same supercontinent Gondwana, that got segregated into countries giving rise to the globe we know today. Antarctica had a warmer climate until then. Despite human civilisation around the globe, it still remains in it pure form. Being a south Indian sun-worshipping guy, it was unimaginable for the author to visit the place that constitutes world’s 90 per cent of ice, a place so quiet that it is only interrupted by snow avalanches. It is home to a lot of evidences that can give us a glimpse of the past and at the same time, Antarctica helps us foresee the future. The place gives an awakening to threatening alarm that global warming is actually real. Who knows if Antarctica will be warm again and even if it does, will we be alive to see it?

    Journey to the end of the Earth Summary in Hindi

    मद्रास से अंटार्कटिका की यात्रा करने वाले एक दक्षिण भारतीय व्यक्ति के लिए, वहां तक ​​पहुंचने के लिए नौ समय क्षेत्र, छह चौकियां, तीन जल निकाय और उतने ही पारिस्थितिक क्षेत्र लगते हैं। तिशानी दोशी ने ‘स्टूडेंट्स ऑन आइस’ नामक एक अभियान समूह के साथ पृथ्वी के दक्षिणी छोर की यात्रा की, जो युवा दिमागों को दुनिया में हो रहे जलवायु परिवर्तन के यथार्थवादी संस्करण के प्रति संवेदनशील बनाने का अवसर प्रदान करता है। संगठन के संस्थापक के अनुसार, हम भविष्य के नीति निर्माताओं के युवा संस्करण हैं जो स्थिति को बदल सकते हैं। अंटार्कटिका दुनिया के सबसे ठंडे, सबसे शुष्क और हवा वाले महाद्वीपों में से एक है।

    जहां तक ​​आंखें देख सकती हैं, यह पूरी तरह से सफेद है और इसका निर्बाध नीला क्षितिज बेहद राहत देता है। यह विश्वास करना चौंकाने वाला है कि भारत और अंटार्कटिका उसी सुपरकॉन्टिनेंट गोंडवाना का हिस्सा थे, जो आज हम जिस विश्व को जानते हैं, उसे जन्म देने वाले देशों में विभाजित हो गए हैं। उस समय तक अंटार्कटिका की जलवायु गर्म थी। दुनिया भर में मानव सभ्यता के बदलाव के बावजूद यह अभी भी अपने शुद्ध रूप में बनी हुई है। दक्षिण भारतीय सूर्य-पूजा करने वाले व्यक्ति होने के नाते, लेखक के लिए उस स्थान का दौरा करना अकल्पनीय था, जो दुनिया की 90 प्रतिशत बर्फ का निर्माण करता है, एक ऐसा स्थान जो इतना शांत है कि यह केवल हिमस्खलन से बाधित है। यह बहुत सारे सबूतों का घर है जो हमें अतीत की एक झलक दे सकता है और साथ ही, अंटार्कटिका हमें भविष्य की भविष्यवाणी करने में मदद करता है। यह जगह खतरनाक अलार्म को जागृत करती है कि ग्लोबल वार्मिंग वास्तव में वास्तविक है। कौन जानता है कि अंटार्कटिका फिर से गर्म होगा और अगर ऐसा होता भी है, तो क्या हम इसे देखने के लिए जीवित रहेंगे?

    Journey to the end of the Earth Lesson Explanation

    EARLY this year, I found myself aboard a Russian research vessel — the Akademik Shokalskiy — heading towards the coldest, driest, windiest continent in the world: Antarctica. My journey began 13.09 degrees north of the Equator in Madras, and involved crossing nine time zones, six checkpoints, three bodies of water, and at least as many ecospheres.
