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.
