Short Answer TypeGive reasons for the following:
(i) The North East Monsoons bring almost no rain to most of India.
(ii) The mango showers are beneficial local winds.
(iii) The latitudinal extent of India is responsible for the variation in the climatic conditions which prevail in the country.
(i) The North East Monsoons bring almost no rain to most of India because these winds have no moisture, as they blow from land to sea.
(ii) ‘Mango showers’ are beneficial local winds because the little rainfall which they bringis important lor the growth ol mango, lea and coffee plants’m’Kera’la and the coasts of Karnataka.
(iii) India stretchers over a large latitudinal extent is responsible for the climatic change and controls the climate all over India. Tropic of Cancer divides India into two heat zones, Tropical and Temperate zone. Peninsular India is in Tropical zone, this belt is close to equator and is also surrounded by water bodies so it has moderating affect of sea. But the northern part which is temperate zone has a different climate, because this belt is away from the equator and also away from the influence of sea, thus has extremes of climate. Its extremely high temperature in summer, attracts S.W. monsoon winds, thus is responsible for rains all over the country.
