Question

Arrange the following processes into sequential order for cyclone formation over the open ocean:

• A. B, A, C, D, E
• B. B, A, C, E, D
• C. A, B, C, D, E
• D. A, B, D, E, C

Hint:

Cyclone formation sequence: warm moist air over ocean rises, cools, condenses, releases heat, and then more air rushes in to create strong winds.

Answer 1

The Correct Option is B

Concept: Cyclones form over warm ocean water when warm moist air rises, cools, condenses, releases heat, and creates a low-pressure system with strong winds.

Step 1: Start with warm moist air over the ocean.
Cyclone formation begins when warm moist air moves over the warm ocean surface. \[ B = \text{Warm moist air moves over the ocean} \]

Step 2: Water vapour rises upward.
Because warm air is lighter, it rises into the atmosphere. \[ A = \text{Water vapour rises into the atmosphere} \]

Step 3: Condensation occurs.
As the rising air reaches cooler layers of the atmosphere, it cools and condenses into liquid droplets. \[ C = \text{Cools and condenses into liquid droplets} \]

Step 4: Heat is released.
During condensation, latent heat is released, making the surrounding air warmer and lighter. \[ E = \text{Heat is released} \]

Step 5: More moist air rushes in and winds increase.
As warm air continues to rise, more moist air from the ocean takes its place, creating stronger wind circulation. \[ D = \text{More wind is created} \] Therefore, the correct sequence is: \[ B, A, C, E, D \]
