9.7 Going Deeper (Exam Prep)

Real-world connections

These wonders are not just sights to enjoy; they are living laboratories and shared treasures. Scientists study the Lonar lake to understand meteorite impacts (and even conditions on other planets); botanists study the Valley of Flowers to protect rare species; engineers admire the root bridges as a model of sustainable building. Many such sites are protected as national parks or UNESCO World Heritage Sites. Caring for them — not littering, not damaging plants, supporting conservation — is something every visitor, including students, can do.

Quick Revision Card

  • Form: descriptive non-fiction about India’s natural wonders.
  • Valley of Flowers — Uttarakhand; vibrant Himalayan blooms; snow leopard, flying squirrel.
  • Chandipur Beach — Odisha; sea recedes far at low tide (“hide-and-seek”).
  • Living Root Bridges — Meghalaya; grown from rubber fig roots; grow stronger over time.
  • Lonar Crater Lake — Maharashtra; round lake from a meteorite hitting basalt; rare.
  • Techniques: vivid description; opening/rhetorical questions.
  • Theme: wonder at nature; the importance of preserving it.

Exam Corner

Objective / one-mark questions

  1. In which state is the Valley of Flowers, and when does it bloom?
  2. What is unusual about Chandipur Beach?
  3. From what are the Living Root Bridges made?
  4. How was Lonar Crater Lake formed?
  1. Uttarakhand; it blooms during the monsoon months (roughly May to October). 2. At low tide the sea recedes far out and then returns. 3. From the roots of rubber fig trees. 4. By a meteorite striking basalt rock thousands of years ago.

Short-answer questions (2–3 marks)

  1. Why is the Valley of Flowers considered a paradise?
  2. Why are the Living Root Bridges a good example of working with nature?
  3. Why is Lonar Crater Lake of special interest to scientists?
  1. It bursts into bloom with hundreds of kinds of flowers in vibrant colours against snowy Himalayan peaks, and shelters rare animals like the snow leopard and flying squirrel.
  2. People guide living tree roots into bridges instead of cutting trees or using concrete; because the roots are alive, the bridges grow stronger over time and last for generations.
  3. It is a rare crater formed in hard basalt rock by a meteorite. Such craters are very unusual, so scientists study it to learn about impacts and unusual lake chemistry.

Long-answer questions (5–6 marks)

  1. Describe any two natural wonders from the chapter and explain what makes each special.
  2. How does the writer use description and questions to make the chapter engaging?
  1. Choose two (e.g. Valley of Flowers and Lonar Lake). For each, give location, what it looks like, why it is rare or beautiful, and any special features (wildlife, origin). Use vivid detail.
  2. The writer uses precise, sensory description (vibrant colours, vanishing seas, living bridges) so places come alive, and opens with curious or rhetorical questions that grab attention and make the reader want to read on.

HOTS (Higher-Order Thinking)

  1. The chapter is placed in the unit “Mystery and Magic,” yet it is non-fiction. Why do these real places belong in such a unit?

Although they are real and explained by science, these places feel magical: a sea that disappears, bridges that grow, a lake from outer space. They show that the real world holds mysteries and marvels as astonishing as anything in a story — so they fit perfectly in a unit about mystery and magic.

Assertion–Reason

  1. Assertion (A): The Living Root Bridges grow stronger over time. Reason (R): They are made from living tree roots that keep growing.

Choose: (a) Both A and R true and R explains A; (b) Both true but R does not explain A; (c) A true, R false; (d) A false, R true.

(a) Both statements are true, and R correctly explains why the bridges grow stronger.

A pinch of science

Did You Know? Lonar Crater Lake was formed roughly 50,000 years ago and is one of the few large impact craters in the world found in basalt rock — similar to the volcanic rock on the Moon and Mars. That is why scientists, including space researchers, study it to understand impacts on other worlds.
