21. Which among the following processes of transfer of energy is confined only to the troposphere?
[A] Convection
[B] Conduction
[C] Radiation
[D] Insolation
Show Answer
Correct Answer: A [Convection]

Convection is the process of vertical heating of the atmosphere. The convective transfer of energy is confined only to the troposphere.
22. Which among the following is a source region of air masses?
[A] Equatorial low pressure belt
[B] Sub – tropical high pressure belt
[C] Polar low pressure belt
[D] Sub – tropical low pressure belt
Show Answer
Correct Answer: B [Sub – tropical high pressure belt]
Notes:
The homogenous surfaces, over which air masses form, are called the source regions.
The main source regions are the high pressure belts in the sub tropics (giving rise to tropical air masses) and around the poles (the source for polar air masses).
The source region should be slightly at high pressure.
23. Which among the following statements is/are correct about temperate cyclone?

[B] Only 3
[C] Only 1 & 3
[D] 1, 2 & 3
Show Answer
Correct Answer: D [1, 2 & 3]
Notes:
The Surface Zone is also called as the Photic zone or the Euphoric Zone. It contains about 2 percent of the total volume of water in the ocean. It is limited to a depth of about 100 meters.
Thermocline: It lies between 100 metres and 1000 metres. It contains about 18 percent of the total volume of water in the ocean.
Deep Zone: This zone lies below 1000 metres in the mid-latitudes. This zone contains about 80 percent of the total volume of water in the ocean.
25. Which among the following statements is/are correct about the symbiotic life of Corals?
- Algae gives carbon dioxide and other substances the coral polyp needs.
- Coral polyp gives off oxygen and other nutrients that the algae needs.
Select the correct code from the options given below:
[A] Only 1
[B] Only 2
[C] Both 1 & 2
[D] Neither 1 & 2
Show Answer
Correct Answer: D [Neither 1 & 2]
Notes:
Coral lives a symbiotic life. Inside the sac of each coral polyp lives one-celled algae called zooxanthellae.
Algae gives off oxygen and other nutrients that the coral polyp needs to live and in return the polyp gives the algae carbon dioxide and other substances the algae needs.
