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?The physical map of India that this chapter asks you to keep beside you — redrawn here with its legend and its latitude and longitude lines.
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.
