Daily Static MCQs Quiz for UPSC, IAS, UPPSC/UPPCS, MPPSC. BPSC, RPSC & All State PSC Exams

Subject : Geography

1. Consider the following statements regarding Temperate Rainforests:

1. Temperate rainforests are found mostly in coastal, mountainous areas.
2. Cooler temperatures and a more stable climate slow down decomposition, allowing more material to accumulate.
3. Temperate rainforests are the most biologically diverse terrestrialecosystems in the world.

How many of the above statements is/are correct?

(a) Only one
(b) Only two
(c) All three
(d) None

Answer: (B)

Explanation: Temperate rainforests are located in the mid-latitudes, where temperatures are much more mild than the tropics. Temperate rainforests are found mostly in coastal, mountainous areas. Rainfall in these forests is produced by warm, moist air coming in from the coast and being trapped by nearby mountains. Cooler temperatures and a more stable climate slow down decomposition, allowing more material to accumulate. This productivity allows many plant species to grow for incredibly long periods of time. Tropical rainforests are the most biologically diverse terrestrial ecosystems in the world. Hence, statement 3 is incorrect.

2. Which of the following lake is not part of Great Lakes region of North America?

(a) Lake Ontario
(b) Great Slave Lake
(c) Michigan Lake
(d) Lake Erie

Answer: (B)

Explanation: The Great Lakes also called the Laurentian Great Lakes and the Great Lakes of North America, are a series of interconnected freshwater lakes located primarily in the upper mid-east region of North America, on the Canada–United States border, which connect to the Atlantic Ocean through the Saint Lawrence River. They consist of Lakes Superior, Michigan, Huron, Erie, and Ontario. Hence, option (b) is correct.

3. Which of the following statement best describes ‘Doldrums’?

(a) Frigid zone of the earth where there is little atmospheric circulation.
(b) High pressure area in subtropical region where westerlies originate.
(c) Tropical region in Indian ocean where cyclone often originate.
(d) Belt of calm region in equatorial region where prevailing trade winds meet.

Answer: (D)

Explanation: Doldrums, also called equatorial calms, equatorial regions of light ocean currents and winds within the intertropical convergence zone (ITCZ), a belt of converging winds and rising air encircling Earth near the Equator. The northeast and southeast trade winds meet there; this meeting causes air uplift and often produces clusters of convective thunderstorms. They occur along the Equator in the Indian and western Pacific oceans and slightly north of the Equator off the African and Central American west coasts. Hence, option (d) is correct.

4. Consider the following statements regarding Fold Mountains:

1. Fold Mountains are created when large areas are broken and displaced vertically.
2. They are least likely to have conical peaks.

Which of the above statements is/are correct?

(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2

Answer: (D)

Explanation: Fold mountains are created where two or more of Earth’s tectonic plates are pushed together. At these colliding, compressing boundaries, rocks and debris are warped and folded into rocky outcrops, hills, mountains, and entire mountain ranges. The Himalayan Mountains and the Alps are young fold mountains with rugged relief and high conical peaks. The Appalachians in North America and the Ural Mountains in Russia have rounded features and low elevation. They are very old fold mountains. Block Mountains are created when large areas are broken and displaced vertically. Hence, both statements are incorrect.

5. Which of the following are the conditions for the emergence of a tropical cyclone?

1. Unstable condition through the Troposphere
2. Strong Coriolis force
3. Strong vertical wind
4. Large and continuous supply of warm and moist air.

Select the correct answer using the code given below:

(a) 1, 2 and 3
(b) 1, 2 and 4
(c) 2, 3 and 4
(d) All of the above

Answer: (B)

Explanation: Some initial conditions for the emergence of a tropical cyclone are:

  1. Large and continuous supply of warm and moist air that can release enormous latent heat.
  2. Strong Coriolis force that can prevent filling of low pressure at the centre (absence of Coriolis force near the equator prohibits the formation of tropical cyclone between 0°-5° latitude).
  3. Unstable condition through the troposphere that creates local disturbances around which a cyclone develops.
  4. Finally, absence of strong vertical wind wedge, which disturbs the vertical transport of latent heat.

Hence, option (b) is correct.
