Journey to the End of the Earth Important Short and Long Question Class 12 chapter-3 Book-Vistas

Q-1. How do geological phenomena help us to know about the history of mankind?

Ans: 

Geological phenomena such as glacial movements, shifting of tectonic plates, and fossil records help us understand the history of the Earth and mankind. They provide information about climate changes, ancient species, and past civilizations. For example, studying ice cores in Antarctica helps scientists learn about Earth’s past climate and how it has changed over millions of years.

Q-2. What kind of indications do we get while visiting Antarctica to save Earth?

Ans: 

Antarctica gives us clear warnings about the effects of global warming and climate change. Melting glaciers, thinning ice sheets, and rising temperatures show that climate change is real and dangerous. Studying Antarctica helps scientists understand how human activities are affecting the environment and how we can take steps to save Earth.

Q-3. The world’s geological history is trapped in Antarctica. How is the study of this region useful to us?

Ans: 

Antarctica holds deep ice layers and fossils that reveal Earth’s geological history. By studying these, scientists can:

• Understand past climate patterns.

• Predict future climate changes.

• Learn how species and ecosystems evolved over time.

• See how human activities are affecting the planet.

This research helps us understand how to protect the Earth from further environmental damage.

Q-4. Why is a visit to Antarctica important to realize the effect of global warming?

Ans: 

A visit to Antarctica is important because it shows clear evidence of global warming. The melting glaciers, rising sea levels, and changing weather patterns prove that climate change is happening at an alarming rate. Seeing these changes firsthand makes people more aware of the urgent need to take action to protect the environment.

Q-5. How is Antarctica a crucial element in the debate on climate change?

Ans: 

Antarctica plays a crucial role in climate change discussions because:

• It contains 70% of the world’s freshwater in its ice sheets.

• It reflects the first signs of global warming, like melting ice and rising temperatures.

• Changes in Antarctica affect sea levels worldwide, which can cause floods and natural disasters.

• It helps scientists study how climate change has impacted Earth in the past and what might happen in the future.

Q-6. The author calls her two-week stay in Antarctica ‘a chilling prospect’. How far do you think she is justified? What other features of the Antarctic environment are highlighted?

Ans: 

The author calls her stay in Antarctica "a chilling prospect" because of the extreme cold, harsh weather, and isolation of the continent. She is justified because Antarctica has sub-zero temperatures, strong winds, and no human settlements. Other features highlighted include massive icebergs, vast white landscapes, and unique wildlife like penguins and seals.

Q-7. Why is Antarctica and its understanding important for the survival of the world?

Ans: 

Antarctica is important for Earth’s survival because:

• It regulates global temperatures by reflecting sunlight.

• It holds ancient climate records, helping scientists predict future climate changes.

• If its ice sheets melt completely, sea levels will rise, flooding coastal cities worldwide.

• It provides insights into how we can slow down climate change and protect the environment.

Q-8. What are the indications for the future of humankind?

Ans: 

The indications for the future of humankind are concerning because:

• Glaciers are melting faster than expected, leading to rising sea levels.

• Extreme weather conditions like storms, droughts, and floods are increasing.

• Biodiversity is at risk due to habitat destruction.

• If we do not act soon, climate change will lead to food and water shortages, affecting millions of people.

Q-9. How did Antarctica amaze the writer when she first saw it?

Ans: 

The writer was amazed by Antarctica’s vast, untouched beauty. She was struck by the gigantic icebergs, endless white landscapes, and the pure, silent atmosphere. She found it hard to believe that such a pristine and frozen world existed far away from human civilization.

Q-10. Why was Tishani Doshi filled with relief and wonder when she set foot on the Antarctic continent?

Ans: 

Tishani Doshi felt relief because she had completed the long and difficult journey to Antarctica. She felt wonder because she was stepping into a completely different world—a place with vast ice sheets, unique wildlife, and no signs of human interference.

Q-11. How was the programme, ‘Students on Ice’ an attempt to equip future generations with knowledge to save Earth?

Ans: 

The ‘Students on Ice’ program helps young people understand the impact of climate change by taking them to Antarctica. It teaches them:

• The importance of environmental conservation.

• How human actions affect the planet.

• Why climate change needs urgent action.

By experiencing Antarctica firsthand, these students become future leaders in the fight to protect Earth.
