Question 81. Landmasses are heated and cooled much faster than water bodies. Which of the following statements justifies it?

  1. The land gets heated by conduction.

  2. Water has a higher specific heat.

  3. Only the surface layer of water is heated.

  4. Water gets heated by convection.


  1.    2 and 3
  2.    1, 2 and 3
  3.    1, 2 and 4
  4.    1 and 4
 Discuss Question
Answer: Option C. -> 1, 2 and 4
Answer: (c)
Land masses are heated and cooled much faster than water bodies because land gets heated by conduction and water has a higher specific heat, it gets heated by convection.
Question 82. Which of the following pairs is not correctly matched?
  1.    Zeugen — Wind
  2.    Canyon — River
  3.    Moraine — Glacier
  4.    Inselberg — Glacier
 Discuss Question
Answer: Option D. -> Inselberg — Glacier
Answer: (d)
An inselberg is an isolated rock hill, Knob, ridge or Small mountain that rises abruptly from a gently sloping or virtually level surrounding plain.
Question 83. Normally, the temperature decreases with the increase in height from the Earth’s surface, because

  1. The atmosphere can be heated upwards only from the Earth’s surface.

  2. There is more moisture in the upper atmosphere.

  3. The air is less dense in the upper atmosphere.


Select the correct answer using the code given below.
  1.    2 and 3
  2.    Only 1
  3.    1, 2 and 3
  4.    1 and 3
 Discuss Question
Answer: Option D. -> 1 and 3
Answer: (d)
Question 84. Thunderstorms are associated with
  1.    Cumulonimbus clouds
  2.    Cumulus clouds
  3.    Stratus clouds
  4.    Cirrus clouds
 Discuss Question
Answer: Option A. -> Cumulonimbus clouds
Answer: (a)Cumulonimbus is a heavy, dense cloud mith great vertical growth and responsible for thunderstorms.
Question 85. The atmospheric layer farthest from the Earth’s surface is known as
  1.    Exosphere
  2.    Stratosphere
  3.    Mesosphere
  4.    Ionosphere
 Discuss Question
Answer: Option A. -> Exosphere
Answer: (a)Extending from the top of the thermosphere to 10,000 km above the earth is the exosphere which is farthest from the Earth. This layer has very few atmospheric molecules, which can escape into space.
Question 86. Atmospheric temperature increasing at the higher altitudes is called
  1.    Inversion
  2.    Radiation
  3.    Convection
  4.    Conduction
 Discuss Question
Answer: Option A. -> Inversion
Answer: (a)
The reversal of the normal behaviour of temperature in the troposphere in which a layer of cool air at the surface is overlain by a layer of warmer air is known as temperature inversion.
Inversions play an important role in determining cloud forms, precipitation, and visibility.
Question 87. Assertion (A):
60º-65º latitudes in both the hemispheres have a low pressure belt instead of high pressure.
Reason (R):
The low pressure areas are stable over oceans rather than on land.
Code
  1.    Both (A) and (R) are true, but (R) is not the correct explanation of (A)
  2.    Both (A) and (R) are true and (R) is the correct explanation of (A)
  3.    (A) is false, but (R) is true
  4.    (A) is true, but (R) is false
 Discuss Question
Answer: Option D. -> (A) is true, but (R) is false
Answer: (d)
Question 88. The climatic zones are classified on the basis of
  1.    elevation
  2.    distance from the equator
  3.    distance from the sea
  4.    rainfall
 Discuss Question
Answer: Option D. -> rainfall
Answer: (d)
The climatic zones are classified on the basis of maximum and minimum temperatures and the temperature range as well as the total and seasonal distribution of precipitation.
Based on these parameters, the most commonly used classification scheme was originally developed by Wladimir Koppen.
Question 89. Which of the following are true with regard to temperature control of the atmosphere of a given place?

  1. The major temperature contrasts on the earth’s surface are between landmasses and oceans.

  2. During the night, the water surface cools more rapidly than the land surface.

  3. Temperature generally decreases with latitude on either side of the equator.

  4. The temperature rises to a maximum during summer and falls to a minimum during winter.


  1.    2, 3 and 4
  2.    1, 3 and 4
  3.    3 and 4
  4.    1 and 2
 Discuss Question
Answer: Option B. -> 1, 3 and 4
Answer: (b)
Question 90. Examine the following statements and select the correct answer using the codes given below:

  1. The atmospheric air is never completely dry.

  2. Water vapour can occupy as much as 4 per cent of the atmospheric volume.

  3. Water vapour in the atmosphere is always invisible.


Codes:
  1.    2 and 3 are correct
  2.    1 and 2 are correct
  3.    1, 2 and 3 are correct
  4.    1 and 3 are correct
 Discuss Question
Answer: Option B. -> 1 and 2 are correct
Answer: (b)
Water vapour in the atmosphere is visible
