Convection is the rising motion of warmer areas of a liquid or gas, and the sinking motion of cooler areas of liquid or gas, sometimes forming a complete cycle. However, it is often difficult to see, particularly within the air.
Explanation:
the hot air has low pressure and cold air has high pressure for an example :-
1) low pressure:- when you boil water the hot air moves upwards because of low pressure.
2) high pressure:- in you refrigerator the cooling system is fix on upside. because the cold air have high pressure and high pressure air come downward it cool all the part of refrigerator.
as same as
when the land becomes hot air become low pressure wind as low pressure wind moves upwards the space become blank and we want some air to fill it so the high pressure wind come cover the place and when the cold air turns into hot the air moves upwards and become cold and this cycle repeats infinite time.
as the diagram was given in your book.
