“The wind flows from high pressure areas to low pressure areas” – interpret the statement.

Answer»
  • When any part of the earth heats up and causes low pressure, it means that there is more vacant space and less molecules. 
  • Now air from other parts where the pressure is higher moves towards this vacant place. 
  • It is not difficult for the wind to move along the earth’s surface and thus need not go too much against gravity any more.
  • That is why the wind flows from high pressure areas to low pressure areas.
