Short Type Questions Extra Questions (Marks-2)
(1) What are the factors that control Indian climate?
A: latitude, altitude, pressure and wind system, distance from the sea, ocean currents and relief features.
(2) What is the role of latitude in controlling the Indian climate?
A:due to the curvature of the earth the amount of solar energy received varies according to the latitude. as a result air temperature generally decreases from the equator towards the poles.
(3) What is the role of pressure and wind system in controlling climate?
A: the pressure and wind system of any area depend on the latitude and altitude of the place. Does it influences the temperature and rainfall pattern.
(4) What is the role of distance from the sea in controlling the climate?
A: the sea exerts a moderating influence on the climate. As the distance from the sea increases,its moderating influence decreases and the people experience extreme weather condition.
(5) What is the role of ocean currents in controlling the climate?
A: ocean currents along with on shore winds affect the climate of the coastal areas. For example, any coastal area with warm or cold currents flowing past it, will be warmed or cooled if the winds are on shore.
(6) How do relief plays an important role in controlling climate?
A: relief plays a major role in determining the climate of a place. High mountains act as barriers for cold or hot winds. They may also cause precipitation if they are high enough and lie in the path of rain bearing winds. The leeward side of the mountains remain comparatively dry.
(7) why India’s climate has characteristics of tropical as well as subtropical climates?
A: the tropic of Cancer passes through the middle of the country from the rann of Kutchhin the west to mizoram in the East. Almost half of the country, lying south of the tropic of Cancer, belongs to the tropical area. All the remaining area, north of tropic of Cancer, lies in the subtropics. Therefore India’s climate has characteristics of tropical as well as subtropical climates.
(8) On which atmospheric conditions the climate of India depends?
A: 1) pressure and surface winds 2) upper air circulation and 3) Western cyclonic disturbances and tropical cyclones.
(10) Why do the north easterly range bring little or no rain at all?
A: because these winds carry little moisture as they originate and blow over land.
(11) What is coriolis force?/what is ferrel’s law?
A: the coriolis force is an apparent force caused by the earth’s rotation. The coriolis force is responsible for deflecting winds towards the right in the northern hemisphere and towards the left in the southern hemisphere. This is also known as ferrel’s law.
(12) What are Southwest monsoon winds?
A: yeah moves from high pressure area over the southern Indian ocean, in south easterly direction, crosses the equator,and turns right towards the low pressure areas over the Indian subcontinent.These are known as South West monsoon winds.
(13) What are jet streams?
A: jet streams are narrow belt of high altitude westerly winds in the troposphere. The speed vary from about 110 kilometre per hour in summer to about 184 kilometre per hour in winter.
(14) What are subtropical westerly jet streams?
A: this jet streams are located approximately over 27°-30°N latitude, therefore they are given this name. Over India, these jet streams blow south of the Himalayas, all through the year except in the summer.the Western cyclonic disturbances experienced in the north and North Western parts of the country are brought in by this westerly flow.
(15) What is ITCZ?
A: the intertropical convergence zone is a broad trough of low pressure in equatorial latitudes. This is where the north east and the south east trade winds converge. This convergence zone lies more or less parallel to the equator but moves North or South with thethe apparent movement of the sun.
(16) What is El nino?
A:El nino is a name given to the periodic development of warm ocean currents along the coast of Peru as a temporary replacement of the cold peruvian current. El nino is a Spanish word meaning ‘the child’ and refers to the baby Christ,as this current starts flowing during Christmas.the presence of El nino leads to an increase in sea surface temperatures and weakening of the trade winds in the region.
(17) What are burstsof the monsoons?
A: around the time of of the onset of of monsoon, the normal rainfall increases suddenly and continuous constantly for several days. This is known as burst of the monsoon.
(18) What is the expansion of cold weather season in India?

(21) What is loo?
A: Loo is a striking feature of the hot weather season in India. These are strong hot and dry winds blowing during the day over the north and North Western India. Sometimes they even continue until late in the evening. Direct exposure to these winds may even prove to be fatal.
