1. ‘The world’s geological history is
trapped in Antarctica.’ How is the study of this region useful to us?
Answer:
Antarctica's strata of ice contain half-million-year-old carbon track records.
It teaches us about evolution and extinction, as well as ozone and carbon. A
trip to Antarctica, where Gondwana previously lived, is like stepping back in
time. Observing geological occurrences, such as landmasses moving and spreading
into countries, allows us to learn more about human history. These are obvious
traces of where people originated from, and they help us comprehend where human
life will go if we do not protect the environment. Seeing all of these changes
with our own eyes confirms that global warming is a serious issue.
2. What are Geoff Green’s reasons for including
high school students in the Students on Ice expedition?
Answer:
Students, according to Geoff Green, are the next generation of policymakers.
They should be given the chance to undergo this life-changing experience when
they are young in order to build fresh knowledge and respect for our world. It
would assist people in absorbing, learning, and acting in the best interests of
the planet. Young people still have the idealistic desire to save the world,
but they must recognise that it is theirs. As a result, it is critical to
present them with a visible life-changing experience in order to sensitise
them.
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 saying implies that if tiny things are looked after, big things will look
after themselves. In the southern waters, long grasses called phytoplankton to
use the sun's energy to ingest carbon and produce organic molecules through
photosynthesis. These tall grasses provide food for the region's marine life
and birds. Any change in Antarctica's environment may have an impact on
phytoplankton activity, which in turn may have an impact on the existence of
other living forms that rely on them. Phytoplankton, for example, plays a vital
role in the food chain.
4. Why is Antarctica the place to go to,
to understand the earth’s present, past and future?
Answer:
According to the author, Antarctica is the ideal location for learning about
the earth's present, past, and future. Because it has never had a human
population, Antarctica is comparatively unspoiled in this regard. It's in a
good state of repair. Half a million-year-old carbon records are preserved in
the layers of ice in its ice cores. It encapsulates everything prehistoric:
cordilleran folds, pre-Cambrian granite shields, ozone and carbon, evolution
and extinction. The lack of biodiversity and basic ecosystem demonstrates how
minor environmental changes can have significant consequences.
When we visit Antarctica and see geological
processes like land masses moving, glaciers melting, and ice shelves crumbling,
we realise that global warming is a serious concern. As a result, Antarctica is
the finest area to research the earth's past, present, and future because of
these facts.
