SSC CHSL 2023 PYQ — Question 39

SSC CHSL - 09 March 2023 - Shift 1 • General Awareness • Q39

Which of the following statement is correct regarding air pressure?

Show answer & explanation

Correct answer: C

Explanation

The correct answer is Option 3 i.e. The air always moves from high pressure areas to low pressure areas.

  • Air naturally flows from regions of high pressure to regions of low pressure due to pressure differences.

  • This movement helps balance atmospheric pressure and is the fundamental cause of wind.

  • High-pressure areas have denser, more stable air, while low-pressure areas have lighter, less stable air.

  • The flow of air creates different weather patterns, such as clear skies in high-pressure zones and clouds or storms in low-pressure zones.

  • Understanding this movement is crucial in meteorology and weather forecasting.

Explanation of other options 

  • Option 1 is incorrect because high pressure is usually associated with clear, dry weather, not cloudy skies or wet weather.

  • Option 2 is wrong as low pressure areas generally bring clouds and precipitation, not clear and sunny skies.

  • Option 4 is incorrect since air pressure is highest at sea level and decreases with altitude, not the other way around.

  • Hence, only option 3 accurately describes the behavior of air pressure and movement.
