Answer: Option B. -> 4 3 2 1
Answer: (b)
The Santa Ana winds are strong, extremely dry down-slope winds that originate inland and affect coastal Southern California and northern Baja California.
A Chinook wind is a weather phenomenon that creates warm, dry air that blows down the eastern slopes of the Canadian Rockies. The name Chinook means “snow eater,” as the wind occurs most frequently in winter and can disrupt snowstorms and melt fallen snow.
A föhn or foehn is a type of dry, warm, down-slope wind that occurs in the lee (downwind side) of a mountain range. Föhn can be initiated when deep low pressures move into Europe drawing moist Mediterranean air over the Alps. Zonda wind is a regional term for the foehn wind that often occurs on the eastern slope of the Andes, in Argentina.
The Zonda is a dry wind (often carrying dust) that comes from the polar maritime air, warmed by descent from the crest, which is approximately 6,000 m (20,000 ft) above sea level.

  1.    Magnetic field
  2.    Temperature
  3.    Pressure
  4.    Rotation of the Earth

Question 65. Mist is a result of which one of the following
  1.    Evaporation
  2.    Condensation
  3.    Saturation
  4.    Sublimation
 Discuss Question
Answer: Option B. -> Condensation
Answer: (b) Mist is a thin fog resulting from condensation in the air near the earth’s surface.
Question 66. The velocity of the winds is determined by
  1.    pressure gradient and humidity
  2.    pressure gradient
  3.    pressure and earth’s rotation
  4.    coriollis effect
 Discuss Question
Answer: Option B. -> pressure gradient
Answer: (b)
Question 67. A sudden fall of Mercury in Barometer indicates
  1.    Stormy weather
  2.    Fair weather
  3.    Hot weather
  4.    Cold weather
 Discuss Question
Answer: Option A. -> Stormy weather
Answer: (a)
Question 68. Westerlies in Southern Hemisphere are stronger and persistent than in Northern Hemisphere because

  1. Southern Hemisphere has less landmass as compared to Northern Hemisphere.

  2. Coriolis force is higher in Southern Hemisphere as compared to Northern Hemisphere.

Question 69. The solar radiation coming to Earth is called
  1.    Insolation
  2.    Radiant energy
  3.    Terrestrial radiation
  4.    Sunshine
 Discuss Question
Answer: Option A. -> Insolation
Answer: (a)
Insolation is the solar radiation that reaches the earth’s surface. It is measured by the amount of solar energy received per square centimetre per minute.
Insolation affects temperature. The more the insolation, the higher the temperature. On any given day, the strongest insolation is received at noon.
The insolation into a surface is largest when the surface directly faces the Sun. As the angle increases between the direction at a right angle to the surface and the direction of the rays of sunlight, the insolation is reduced in proportion to the cosine of the angle.
Question 70. Which one of the following pairs is not correctly matched?
  1.    Bora - Poland
  2.    Foehn - Alps Mountain
  3.    Khamsin – Egypt
  4.    Mistral - Rhine Valley
 Discuss Question
Answer: Option A. -> Bora - Poland
Answer: (a)
