2. Question
2 points2. Consider the following:
Assertion: Tropical cyclones are not formed near the equator.
Reason: The Coriolis force is maximum at the equator.
Correct
Answer: C
Explanation:
- At the equator, the Coriolis force is zero and the wind blows perpendicular to the isobars. The low pressure gets filled instead of getting intensified. That is the reason why tropical cyclones are not formed near the equator.
Incorrect
Answer: C
Explanation:
- At the equator, the Coriolis force is zero and the wind blows perpendicular to the isobars. The low pressure gets filled instead of getting intensified. That is the reason why tropical cyclones are not formed near the equator.

Which of the statements given above is/are correct?
Correct
Answer: D
Explanation:
- Statement 1 is incorrect: The air circulation around the low-pressure northern hemisphere is always in an anti-clockwise manner.
- Statement 2 is incorrect: The air circulation around high pressure in the northern hemisphere is always in a clockwise manner.
Incorrect
Answer: D
Explanation:
- Statement 1 is incorrect: The air circulation around the low-pressure northern hemisphere is always in an anti-clockwise manner.

4. Question
2 points4. In which of the following cases there is the formation of spring tide is observed on the earth’s surface?
Correct
Answer: A
Explanation:
- Spring tide: When the sun, the moon and the earth are in a straight line, there is formation spring tide. It happens twice a month, one on full moon period (When the earth is located in between the moon and the sun) and another during new moon period (When the moon is located in between the earth and the sun).
- Neap tide: It happens when the sun and moon are at right angles to each other and the forces of the sun and moon tend to counteract one another. Normally, there is a seven-day interval between the spring tides and neap tides.

Question 5 of 5
5. Question
2 points5. Which of the following areas is/are considered as good fishing grounds of the world?
- Mixing of warm and cold ocean currents
- Upwelling of cold ocean water
- Downwelling of warm water
Select the correct answer using the code given below:
Correct
Answer: B
Explanation:
- The mixing of warm and cold currents help to replenish the Oxygen and favour the growth of planktons, the primary food for the fish population. The best fishing grounds of the world exist mainly in these mixing zones.
- Subsurface water that rises to the surface as a result of upwelling is typically colder, rich in nutrients, and biologically productive. Therefore, good fishing grounds typically are found where upwelling is common.
