World & Physical Geography MCQs
World Geography Multiple Choice Questions (MCQs) Quiz for State and UPSC Civil Services Examinations. Objective Questions on Physical Geography and World Geography for competitive examinations.
21. Which process is important in heating the lower layers of the atmosphere?
[A] Insolation
[B] Radiation
[C] Conduction
[D] Convection
Show Answer
Correct Answer: C [Conduction]
Notes:
Conduction is the heat transfer through matter by molecular activity. The air in contact with the land gets heated slowly and the upper layers in contact with the lower layers also get heated. This process is called conduction. Conduction takes place when two bodies of unequal temperature are in contact with one another; there is a flow of energy from the warmer to cooler body.
22. What is the process of transformation of water vapour into water?
[A] Evaporation
[B] Humidity
[C] Sublimation
[D] Condensation
Show Answer
Correct Answer: D [Condensation]
Notes:
Condensation is the process of transformation of water vapour into water. It is caused by loss of heat when moist air is cooled.
If water vapour directly condenses into solid form, it is known as sublimation
23. Which among the following statements is not correct about cyclones?
[A] Cyclones rotate anti-clockwise in Northern Hemisphere and clockwise in Southern Hemisphere.
[B] Cyclone is any low-pressure area with winds spiralling inwards
[C] About 65 per cent of cyclonic activity occurs between 10° and 20° latitude.
[D] They are mostly formed in eastern tropical oceans
Show Answer
Correct Answer: D [They are mostly formed in eastern tropical oceans]
Notes:
Tropical cyclones form mostly on the western margins of the oceans.
They don’t form in the eastern tropical oceans because the cold currents lower the surface temperatures of the eastern parts of the tropical oceans making them unfit for the breeding of cyclonic storms.
24. Which among the following statements is/are correct about Terrigenous Deposits?
- Terrigenous deposits are derived from the wear and tear of land and volcanic and organic products.
- The volcanic deposits are made of pyroclastic volcanic products, quartz and lava.

[A] Only 1
[B] Only 2
[C] Both 1 & 2
[D] Neither 1 & 2
Show Answer
Correct Answer: A [Only 1]
