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:
Amount of insolation decreases from equator torwards poles? Answer: (i) 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 to dry on a humid day.
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 at a faster or normal rate, so they take a long time due to these reasons.
Amount of insolation decreases from equator towards poles. Why? Answer: Sunlight falls almost vertically on the equator, while it falls at slanting angle on the poles. Due to this, amount of insolation decreases from equator towards poles.
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. 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.
