Question 1. Which of the following continents has all types of climatic zones?
  1.    North America
  2.    South America
  3.    Asia
  4.    Australia
 Discuss Question
Answer: Option C. -> Asia
Answer: (c)
Question 2. The planetary winds that blow from the sub-tropical high pressure belts to the equator are known as
  1.    doldrums
  2.    westerlies
  3.    trade winds
  4.    polar winds
 Discuss Question
Answer: Option C. -> trade winds
Answer: (c)Trade winds blow from the subtropical highs or horse latitudes toward the low pressure of the ITCZ(Intertropical Convergence Zone).
Question 3. The forests which act as barriers against cyclones are :
  1.    Mangrove forests
  2.    Alpine forests
  3.    Monsoon forests
  4.    Evergreen forests
 Discuss Question
Answer: Option A. -> Mangrove forests
Answer: (a)
Mangrove Forest acts as barriers against cyclones and other natural disasters like tidal waves and tropical storms. They act as live sea walls against disasters and help minimise the damage done to property and life.
They also slow soil erosion and stabilize tidal banks against rising sea level, another climate change hazard.
Question 4. Troposphere is the hottest part of the atmosphere because
  1.    there are charged particles in it
  2.    it is closest to the Sun
  3.    heat is generated in it
  4.    it is heated by the Earth’s surface
 Discuss Question
Answer: Option D. -> it is heated by the Earth’s surface
Answer: (d)The lowest part of the troposphere is the warmest because it is closest to the ground, where the heat is coming from.
Question 5. The earth’s reflectivity of solar radiation, termed albedo, is highest in which one of the following?
  1.    Forest area
  2.    Cropland
  3.    Snow area
  4.    Sand desert
 Discuss Question
Answer: Option C. -> Snow area
Answer: (c) The percentage of radiant energy reflected back by a surface is called the albedo. The total amount of energy lost by scattering and reflection of various kinds and returned to space is called earth’s albedo.

The climate, to which this data is related to,
  1.    China Type
  2.    St. Lawrence Type
  3.    Mediterranean Type
  4.    Western European Type
 Discuss Question
Answer: Option D. -> Western European Type
Answer: (d)
Question 7. If the earth did not have an atmosphere, temperature extremes between day and night would
  1.    decrease
  2.    increase
  3.    fluctuate rapidly
  4.    stay the same
 Discuss Question
Answer: Option B. -> increase
Answer: (b)If a planet has no atmosphere, all of the sunlight which strikes it reaches the surface, and usually 90% or more of that is absorbed and 10% or less is reflected back into space. Thus the temperature will increase.
Question 8. Land and sea-breezes occur due to :
  1.    Convection
  2.    Conduction
  3.    Tides
  4.    Radiation
 Discuss Question
Answer: Option A. -> Convection
Answer: (a)
During the day, the sun warming the land also warms the air. Since land heats up quicker than water does, the air over land gets warmer than the air over the water. Consequently, the warmer air, being less dense moves up.
To fill its place the cooler air over the water moves in to fill its place creating what is known as a Sea Breeze. Reversely, at night the land cools down faster than the water does, and creates a Land Breeze.
Question 9. The seasonal reversal of winds is the typical characteristic of
  1.    Mediterranean climate
  2.    Equatorial climate
  3.    All of the above climates
  4.    Monsoon climate
 Discuss Question
Answer: Option D. -> Monsoon climate
Answer: (d)
Question 10. Which of the following scales is used to measure the damage by a hurricane?
  1.    Mercalli Scale
  2.    Saffir-Simpson Scale
  3.    Richter Scale
  4.    Fujita Scale
 Discuss Question
Answer: Option B. -> Saffir-Simpson Scale
Answer: (b)The saffir – Simpson Scale estimates potential property damage by a hurricane.
