The circulatory motion of descending cool air and ascending warm air is known as convection.
Because of the circulatory motion of the Earth and the varying amounts of heat that different regions of the world experience, diverse weather patterns, jet streams, deserts, and prevailing winds exist. Heat is transferred through convection, which is the large-scale movement of molecules inside gases and liquids.
Conduction is used to move heat from the object to the fluid initially, but fluid motion is responsible for the bulk of the heat transfer. Convection can occur naturally or artificially. The phenomenon of the sea and land breeze is one of the most prevalent examples of natural convection.
