  3.    Trade winds
  4.    Drainage winds
 Discuss Question
Answer: Option D. -> Drainage winds
Answer: (d)
Question 352. Wind is often found to blow in a hot summer day due to
  1.    radiation from the soil
  2.    conduction of heat between air and soil on the Earth
  3.    None of the above
  4.    convection current of air
 Discuss Question
Answer: Option B. -> conduction of heat between air and soil on the Earth
Answer: (b)Wind is often found to blow in a hot summer day due to conduction of heat between air and soil on the Earth.
Question 353. Mist is a result of which one of the following
  1.    Evaporation
  2.    Condensation
  3.    Saturation
  4.    Sublimation
 Discuss Question

Answer: (b)Mist is a thin fog resulting from condensation in the air near the earth’s surface.
Question 354. Which of the following wind is blowing from the Mediterranean sea to the North-Western parts of India?
  1.    Norwesters
  2.    Western disturbances
  3.    Mango showers
  4.    Loo
 Discuss Question
Answer: Option B. -> Western disturbances
Answer: (b)
Western Disturbance is an extratropical storm originating in the Mediterranean region that brings sudden winter rain to the northwestern parts of the Indian subcontinent.
Jet streams play an important role in bringing these disturbances to India. Western disturbances are generally active from December to February.
Question 355. The layers of the atmosphere are given in the figure. The layer marked ‘A’ refers to :
  1.    Mesosphere
  2.    Troposphere
  3.    Ionosphere
  4.    Stratosphere
 Discuss Question
Answer: Option D. -> Stratosphere
Answer: (d) Stratosphere is the second layer of the atmosphere, extends to a height of 50 km above the earth.
Question 356. Which of the following is FALSE with respect to rainwater harvesting?
  1.    It helps raising water table.
  2.    It is a device of water conservation.
  3.    It increases run-off losses.
  4.    It helps meet rising water demand.
 Discuss Question
Answer: Option C. -> It increases run-off losses.
Answer: (c)
Rainwater harvesting is a technique used for collecting, storing, and using rainwater for landscape irrigation and other uses. It reduces water runoff, improves infiltration and increases the water storage capacity of the soil.
By reducing the runoff, reduces flooding of water on the roads, improves the quality of water and reduces the chances of soil erosion.
Question 357. The graph given below shows the mean average monthly temperatures (in ºC) and mean monthly rainfall (in cm) of a place. This graph is indicative of which one of the climatic zones of the world?
  1.    Rainy tropical
  2.    Wet and dry tropical
  3.    Temperate marine
  4.    Semi-arid tropical
 Discuss Question
Answer: Option B. -> Wet and dry tropical
Answer: (b)
Question 358. Which of the following winds is called anti-trade wind?
  1.    Cyclone
  2.    Chinook
  3.    Westerlies
  4.    Typhoon
 Discuss Question
Answer: Option B. -> Chinook
Answer: (b)
Westerlies are rather stormy and variable though the main direction remains from west to east. But as their general direction is from the west, they are called the “Westerlies”.
They are also known as “Anti-Trade Winds”, because their movement is in the opposite direction from that of the trade wind.
Question 359. Consider the following statements :

  1. Half the water vapour in the air in the atmosphere lies below an altitude of 1000 m.

  2. The amount of precipitable water in the atmosphere increases from the equator to the poles.


Which of the statements given above is/are correct?
  1.    Only 2
  2.    Only 1
  3.    Neither 1 nor 2
  4.    Both 1 and 2
 Discuss Question
Answer: Option C. -> Neither 1 nor 2
Answer: (c)
Half the water vapour in the air in the atmosphere lies below an altitude of 2 kilometres and 90 per cent of water vapour lies below an altitude of 5 kilometres.
The amount of precipitable water in the atmosphere increases from the poles to the equator.
Question 360. Study the following diagrams, A and B. A B High 1020 1015 1015 Low 1005
  1.    A is an anti-cyclone in the southern hemisphere
  2.    A is cyclone in the southern hemisphere
  3.    B is an anti-cyclone in the northern hemisphere
  4.    B is a cyclone in the northern hemisphere
 Discuss Question
Answer: Option D. -> B is a cyclone in the northern hemisphere
Answer: (d)
