Short question answers

	Q1 How do geological phenomena help us to know about the history of mankind? (CBSE 2000, 2009) Ans Geological occurrences help us learn more about human history since they are the only way to grasp the Earth's past, present, and future. What life was like previously and how it has changed throughout time. Scientists believe that beneath the strata of Antarctica lies the world's geological past. Q3 Akademik Shokalskiy was heading towards Antarctica, why? Ans The Russian ship Akademik Shokalskiy, commanded by Canadian Geoff Green, was headed towards Antarctica with a 52-person crew to research and explore human history. Q5 After reaching Gondwana, what were the students’ reactions? Ans They were ecstatic since they were in a remote corner of the planet with no human population and a peaceful environment; it was devoid of flora, signs, and buildings.Q6 Gondwana existed before six hundred and fifty million years ago. Explain. Ans A gigantic merged Southern supercontinent called Gondwana existed approximately 650 million years ago, centered on present-day Antarctica. Meteorites falling to Earth smashed or split the Gondwanan continents. And the fragments of Gondwana combined to form a new continent. As a result, they represent the world's seven continents. Q7 How does Antarctica factor into environmentalists’ debates? Ans Antarctica is frequently discussed by environmentalists since it is the only continent unaffected by human activities. Concerns have been raised regarding whether it will melt, how it will effect the Gulf Stream ocean movement, and whether it will bring the planet to an end. Q9 Why is Antarctica the ideal location for studying nature? Ans Antarctica is an ideal area to study nature since it has a simple environment and a lack of species; most importantly, it is uninhabited by humans. Q10 Why the programme ‘Students on Ice’ became so successful? Ans The program's efficacy stems from the fact that no location near the South Pole can be visited without being affected by it. Students were given educational opportunities through this program. Q11 What justifications does Geoff Green give for bringing high school kids along on the Students on Ice Expedition OR Students on Ice is a programme that prepares global citizens. Discuss. (CBSE QUESTION BANK) Ans Six years after this chapter was published, Canadian Geoff Green launched the Students on Ice programme. Because high school students still had a lot of absorbing, learning, and, most importantly, acting to do, it was critical to include them in the most engaging educational opportunities that would raise awareness of our ecosystem's deterioration and promote a knowledge of how to save our planet. Q12 “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? Ans Antarctica is a good area for research because of its simple ecosystem and lack of fauna. Photosynthesis is performed by single-celled, microscopic phytoplankton using energy from the Sun. Furthermore, any hindrance to this process will have an influence on both the global carbon cycle and the survival of all local birds and marine mammals. Experts warn and urge that if the small things are taken care of, the big ones will follow. Q13 Why is Antarctica the best site to visit in order to comprehend the past, present, and future of the earth? (CBSE 2010) Ans Antarctica is currently the only region on Earth that is in its purest and most natural state, with carbon records preserved in its ice layers dating back 500,000 years. Because it has never supported a human population, Antarctica is still considered relatively "pristine" in this sense. To understand the past, present, and future of Earth, one must visit to Antarctica. Q14 For the narrator, spending two weeks in Antarctica is a challenge not only for the body but also the mind. Elaborate. (CBSE QUESTION BANK) Ans Throughout their two-week trek to Antarctica, the narrator of "Journey to the End of the World" faces both physical and psychological challenges. It's difficult to have a positive attitude because of the harsh weather and isolation, and it's perplexing because of the darkness and lack of markers.
