Reading with insight

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

Answer-The study of Antarctica is useful to us in a very mysterious and enigmatic way. six and a half million years ago; Gondwana' was a supercontinent, centered roughly around present-day Antarctica. The climate was very hot, hosting a vast diversity of flora and fauna. , Gondwana flourished for 500 million years. Around that time, the landmass was forced to separate into countries, shaping the world as we know it today. It helps to understand the importance of Cordilleran Folds and Pre Cambrian Granite Shields, ozone and carbon, evolution and extinction.

Questions 2- What are Geoff Green ‘s reasons for including high school students in the students on ice expeditions ?

Answer- Human civilization on earth is only 12000 years old. But in this short period man has created a lot of confusion here. He has built cities and towns. It has wiped out species to take away the limited resources of this earth for its ever-increasing population. They have created a cover of carbon dioxide around the world by burning fossil fuels. It is slowly but surely increasing the global temperature. Geoff Green joins his campaign to provide students with inspiring educational opportunities.

Question-3 – Take care of the small things and the big thing will take care of themselves . what is the relevance of this statement in the context of the Antarctic environment ?

Answer- Antarctica, due to its simple ecosystem and lack of biodiversity, is the perfect place to study it, telling us how small changes in the environment can have consequences for the process of photosynthesis, which can be seen under a microscope. called phytoplankton. And any disruption to the process will affect the life of all marine animals and birds in that region, which global carbon cycle scientists warn and recommend to care about the small things and the big things and the big things will collapse.

Question 4- Why is Antarctica the place to go to, understand the earth ‘s present past and future ?

Answer- Antarctica is the only place on Earth that has not supported a human population. Therefore, it remains almost as pure to us as it used to be millions of years ago. There we can see how a slight change can affect the environment. In addition, the half-million-year-old carbon record is trapped in layers of ice. So if we want to study the past, present and future of the earth. Antarctica is the right place.

Shorts answer type Questions

Questions -1 How did the author reach Antarctica ?

  Answer- He travelled in 100 hours in a combination of a car, an aeroplane and a ship. This is how they reached Antarctica.

      Questions 2- What was the wonder author realized reaching Antarctica ?

Answer-The expansive white landscape and the uninterrupted blue horizon and its vastness and isolation was what was wonderful about Antarctica.

Questions 3- What was Gondwana ?

Answer-Six hundred and fifty million years ago, a vast amalgamated southern supercontinent Gondwana actually existed, roughly centered around present-day Antarctica.

Questions -4 How is the present globe shaped which we know today ?

Answer- Gondwana was forced to be divided into countries. The globe was shaped as we know it today. A cold circumpolar current was created.

Questions -5 what can be mind boggling thing about the history in a million years ?

Answer- When we think about all that could happen in a million years, it can get pretty mind-blowing. Imagine India moving north, jamming its crush against Asia to form and form the Himalayas, with South America drifting to join North America.

Question 6- what is chilling prospect for the author ?

Answer-Tihsani Doshi is a South Indian sun worshiper and spends two weeks in a place where 90% of the Earth's total ice volume is stored, not only for circulatory and metabolic function, but also for imagination. A chilling one, likely.

Questions 7- what does one  feel in Antarctica ? How is it captured visually ?

Answer- By going to Antarctica, we can understand the past, present and future of the earth. A trip there can teach the next generation to understand and value our planet. Antarctica also has its half-million year old carbon record which helps us to study climate change by global warming.

Question 8- what is achievement of the human being during the durations of 12000 years .

Answer-Man has been on the earth for about 12000 years and he has created havoc and rocks on this earth. They have done this by encroaching on nature and establishing cities and metros. Their increasing population has depleted the natural resources and their indifference towards nature has led to increase in global temperature.

Questions 9- How can we study and examine the earth past present and future ? How Antarctica play significance role in it ?

Answer- If we travel to Antarctica we will be able to understand the present, past and future of the earth. Let our next generation understand the value of our planet. Antarctica's ice-core has a half-million-year-old carbon record that helps study climate change

Question 10- What was the student one Ice programme ?

Answer-The program was "Students on Ice" with the aim of giving high school students the opportunity of education to study Antarctica.

Questions 11- who was Geoff Green ? What did he offer to the student ?

Answer- Geoff Green was a Canadian explorer and educator , and the founder of the programme  , “Students on Ice” . he started to the include the learner , willing person and school students for the mission and it was also an opportunity for beginners to study more about our planet and ecosystem

Question- 12 what was the reason of the success of the programme ‘ students on Ice’?

Answer-The program was so successful that it became impossible to go anywhere near the South Pole and not be affected by it. Through this program students get educational opportunities..

Question 13- what is photosynthesis ?

Answer- The process of converting light energy into chemical energy by plants is called photosynthesis. .

Question 14 What did the Shokalskiy The Vessel Manage When they reached at 65.55 degree south. ? 

Answer - the Shokalsky had  manage to do is to wrap himself in a thick white strip of snow between the peninsula and Tadpole Island, which was preventing us from going further. The captain decided that we were going to turn around and head back north, but before doing so, we were all instructed to climb the gangplank and walk on the sea.

Question -15 How many members reached at Antarctica and what did they find there ?

Answer-We were all 52, out in gore-tire and glare, walking on the ever-expanding whitewash. Bottom, salt water. Crab seals were stretching around the periphery and drowning themselves on the drift of snow as stray dogs would do in the shade of a banyan tree.
