Q1.
Use the colour code in Fig. 3.8 to add a landform to each name. For instance, ‘Tibetan plateau’, ‘Rocky range’, ‘Nile plain’. (You do not have to remember the names in this map.)Fig. 3.8, page 53 — the world map and its colour code, redrawn.
Answer
The key in Fig. 3.8 gives three colours — brown = plateau, green = river plain, orange = mountain range. Match each name to the colour of the patch it labels:

Ranges (orange): Alaska, Rocky, Andes, Atlas, Ural, Himalaya
Plateaus (brown): Patagonian, East African, Mongolian, Tibetan
River plains (green): Mississippi, Amazon, Nile, Indus, Ganga & Brahmaputra, Yangtze
A pattern worth noticing: every green patch is named after a river — Mississippi, Amazon, Nile, Indus, Ganga, Brahmaputra, Yangtze. That is not a coincidence. River plains are built by rivers, out of the sediments they carry down from the mountains, so the plain naturally takes the river's name.
Another pattern: the orange ranges often sit right beside the green plains — the Himalaya beside the Ganga plain, the Andes beside the Amazon. Mountains supply the rock and silt; the river carries it; the plain is the result.
