4. Give reasons.
(i) Wet clothes take longer time to dry on a humid day?
(ii) Amount of insolation decreases from equator towards poles?
Answers
Answer:
1)Wet clothes take longer time to dry on a humid day because the air has a lot of water vapour and so it can't accomodate the water vapour created by the wet clothes.
2)nsolation comes through vertical rays on equator. Thus, it covers up less space but we feel more heat there when it goes up towards poles, the sun rays become slanting. Needless to say that slanting rays come on the earth covering longer distance. Although, these slanting rays heat up more space, the degree of hotness is felt less. This is the reason why amount of insolation decreases from equator towards poles.

Answer:
1. In humid weather it takes longer time to dry wet clothes because the moisture and water vapour are present in humid weather they gets slight absorbed by the clothes and clothes maintain their wetness due to this they take a longer time to dry and in humid weather they don't get enough sunlight to dry themselves .
When wet clothes dry, the water from the clothes gets evaporated and the water vapour formed from it goes into the atmosphere. On a humid day the air is full of water vapour. Hence, evaporation is very slow.
This is the reason why wet clothes take longer time on a humid day.
2. Insolation comes through vertical rays on equator. Thus, it covers up less space but we feel more heat there when it goes up towards poles, the sun rays become slanting.
