VII. Give reasons
1. Western Coastal plain is narrow.
The western coast plain is narrow because the river flowing through this plain do form any delta. The coastal plain has sand dunes.
2. India has a tropical monsoon climate.
India has a tropical monsoon climate because most of India lies in the tropical belt and her climate is influenced by the monsoon winds which mainly blow in the tropics (20°N and 20°S).
3. Mountains are cooler than the plains.
Mountains are cooler than plains because when the altitude increases, the temperature decreases. Temperature decreases at the rate of 6.5°C for every 1000 metres of ascent.
