why does horizontal destruction of air pressure vary from place to place and season to season? explain two reason
Answers
Answer:
Due to gravity the air at the surface is denser and hence has higher pressure. ... The pressure decreases with height. At any elevation it varies from place to place and its variation is the primary cause of air motion, i.e. wind which moves from high pressure areas to low pressure areas.
Atmospheric pressure varies from place to place and from time to time. This is due to changes in temperature and the quantity of water vapor in the air. The density of moist air is lesser than that of dry air. The density also decreases with an increase in temperature. Hence, the atmospheric pressure also decreases.
The atmospheric pressure at a place is due to the weight of the air above it. Therefore, the pressure will decrease as we go higher above the sea-level. Thus, the atmospheric pressure decreases with increasing altitude.
