(i) Wet clothes take longer time to dry on a humid day?
Answer
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?
