Question

Which of the following statements is/are correct?

• A. A high- pressure region is formed over a place experiencing high temperature.
• B. Air moves from a high-pressure region to a low-pressure region.
• C. A low-pressure region is formed over a place experiencing low temperature.
• D. Atmospheric pressure decreases with increase in altitude.

Answer 1

Answer: (B), (D)

The correct options are
B Air moves from a high-pressure region to a low-pressure region.
D Atmospheric pressure decreases with increase in altitude.

The atmospheric pressure of a region is influenced by both temperature and altitude. With increasing altitude, pressure decreases. In case of temperature, high temperature in an area creates low- pressure region & low temperature creates a high-pressure region.
