Answer :
The correct option is (a) Cool air descends to the ground there is a high-pressure zone.
- At the top of the troposphere, air moves horizontally; this movement is referred to as advection.
- Until it lowers, the air gets cooler. A high pressure zone is produced when the air reaches the ground.
What is an area of high pressure?
- Areas with high pressure are those with relatively thick atmospheres. These regions experience winds, though they spiral outward.
- The air that is still in the high-pressure region progressively falls lower to fill the space left by the ejected air.
In which area air pressure is high?
According to climatology, air that has been lifted at the equator causes high pressure to develop at the horse latitudes,
also known as the torrid zone, between the latitudes of 20 and 40 degrees from the equator.
