Correct Answer: (a) low pressure surrounded by high pressure
Solution:A cyclone is caused by atmospheric disturbances around a low-pressure area and is usually accompanied by violent storms and severe weather conditions.

32. Consider the following statements and select the correct answer with the help of codes given below:

Assertion (A): Hurricane cannot develop in the vicinity of equator.

Reason (R): Coriolis force is maximum over the equator.

Correct Answer: (c) (A) is true, but (R) is false.
Solution:

Hurricanes are unable to form along the equator because of the zero Coriolis Effect at 0 latitude, which is the force required for the spinning motion of these violent storms.

One of the necessary environmental conditions for an atmospheric disturbance to become a full-blown hurricane is for the rough weather conditions to occur at least 300 miles away from the equator.

The Coriolis Effect, which increases from the equator to pole is the apparent force that tends to move rotating objects to the right.
