Question 1 of 5
1. Question
2 pointsWhich of the following conditions is/are conducive for the formation of tropical cyclones?
1. Large and continuous supply of warm and moist air.
2. Large value of Coriolis force.
3. Inflow of air at upper level of atmosphere.Select the correct answer using the code given below:
Correct
ANSWER: A
Explanation:
- Large and continuous supply of warm and moist air is the most important condition for formation of tropical cyclone. Where Coriolis force is zero (like equator), tropical cyclones do not develop. An upper level outflow of air (and not inflow) helps in formation of tropical cyclone.

Question 4 of 5
4. Question
2 pointsWhat is/are the cause/s of low pressure in the equatorial region?
1. High temperature
2. Air convergence
3. High humidity
Select the correct answer using the codes given below:
Correct
ANSWER: A
Explanation:
Due to high temperature, a low pressure belt is created in the equatorial region. This gives rise to air convergence in the area. So, air convergence is the effect of low pressure and not its cause. High humidity has no role to play in generation of low pressure areas.

Explanation:
Due to high temperature, a low pressure belt is created in the equatorial region. This gives rise to air convergence in the area. So, air convergence is the effect of low pressure and not its cause. High humidity has no role to play in generation of low pressure areas.
