(e) Permanent wind
(f) Local wind
(i) Trade Winds – (e) Permanent wind
(ii) Loo – (f) Local wind
(iii) Monsoon – (b) Seasonal wind
(iv) Wind – (c) Horizontal movement of air
Give the Reason for following
(i) Wet clothes take longer time to dry on a humid day?
Wet clothes take longer to dry on a humid day because the air is already saturated with moisture. In high humidity, the air has a higher concentration of water vapor, which makes it difficult for the moisture from the wet clothes to evaporate.
(ii) Amount of insolation decreases from the equator towards poles?
The amount of insolation (incoming solar radiation) decreases from the equator towards the poles. This is because the sunlight at the equator covers a smaller area compared to the sunlight reaching the poles, which is spread over a larger area.
