Q1.
Look at the length of the Himalayan Range on the map. It is like a massive wall. From the legend, can you guess the altitude at different points of the Himalayas?
Answer
On the map the range stretches in a long arc across the whole north. The caption to Fig. 1.2 tells you its length: about 2500 km.
The colours change as you move north across the range, and the legend turns them into heights:
| Part of the range | Colour on the map | Approximate altitude |
|---|---|---|
| Shivalik Hills (Outer Himalayas) | Light brown, just above the green plains | a few hundred to about 1500 m |
| Himachal (Lower Himalayas) | Darker brown | about 1500–4500 m — the hill-station belt |
| Himadri (Greater Himalayas) | Deepest brown, turning to white | above 4500 m, with peaks over 8000 m |
Why it looks like a wall: the height rises steeply over a short north–south distance. You climb from about 200 m on the plains to over 8000 m within roughly 200–300 km, which is why the map shows three colour bands packed tightly together.
Check it yourself: the exact figures depend on the legend printed in your own book — read the height bands there before writing your answer.
