Question

Which of the following is correct when warm air rises up at a place?

• A. The surrounding cold air flows away from that place.
• B. A low pressure region is created at that place.
• C. The surrounding air flows into that place.
• D. A high pressure region is created at that place.

Answer 1

Answer: (B), (C)

The correct options are
B A low pressure region is created at that place.
C The surrounding air flows into that place.

Warm air is lighter than cold air. So when it rises up from a place, a cavity of low pressure is created at that place. Due to this pressure difference surrounding air starts flowing into low pressure region.
