ATMOSPHERIC PRESSURE

ATMOSPHERIC PRESSURE 

Factors Influencing Atmospheric Pressure

  1. Altitude
  • Pressure decreases with increase in altitude because the column of air becomes shorter hence it exerts less weight.
  1. Temperature
  • When air is heated it expands and exerts pressure over a large area resulting in reduced pressure.
  • When it’s cooled it contracts and exerts pressure over a small area resulting in increased pressure.
  1. Rotation of the earth
  • Rotation pushes air masses from poles towards the equator causing air to spread out and occupy more space causing it to expand making pressure to decrease.
  • When air from the equator moves towards the poles it occupies less space causing it to contract resulting into high pressure.
