Consider the following statements about the Atmospheric pressure phenomenon and identify the correct ones. Atmospheric pressure is basically a force in any area pushed by any surface by the weight of the Earth's atmosphere.  The atmospheric pressure increases with an increase in the altitude for any region.  The earth's rotation affects the pressure of the atmosphere in various ways.

Consider the following statements about the Atmospheric pressure phenomenon and identify the correct ones. Atmospheric pressure is basically a force in any area pushed by any surface by the weight of the Earth's atmosphere.  The atmospheric pressure increases with an increase in the altitude for any region.  The earth's rotation affects the pressure of the atmosphere in various ways. Correct Answer Only 1 & 3

The correct answer is Option (3) i.e.Only 1 & 3.

  • Atmospheric pressure:  
    • Atmospheric pressure is basically a force in any area pushed by any surface by the weight of the Earth's atmosphere.
    • Atmospheric pressure decreases with an increase in the altitude for any region.
    • This is because high altitude places do not have sufficient air above them, pushing down.
    • Barometers used to measure the pressure of the atmosphere. 
  • Factors responsible for Atmospheric pressure: 
    • There are some major factors that are usually responsible for atmospheric pressure, which as follows: 
    • Altitude: 
      • Altitude means actual height above the sea level or above it may be above the plain ground.
      • Altitude uses in general in aviation, especially in parachuting, flying, gliding, and in surveying also it is used.
      • In geometry, it is termed as the height of the substance. 
    • Relation of Atmospheric pressure with Altitude: 
      • Atmospheric pressure decreases with an increase in the altitude for any region. Hence, statement 2 is NOT correct.
      • The pressure at any geographical level in the atmosphere may be cumulated as the total weight of the air above one unit area.
      • At higher altitudes, there are a few molecules of air above a specified surface than a similar surface of lower levels. 
  • Earth's Rotation: 
    • The earth's rotation affects the pressure of the atmosphere in various ways.
    • This happens because of the rotation swelling to the near of our equator.
    • The rotation causes a displacement of fluid especially in the hemisphere, which converted to the clockwise direction, is called the Coriolis effect.
