The circular movement of a gas or liquid rising or falling as it becomes hotter or cooler, respectively, is defined as convection. This is the primary process ...
The formation and working of convection cells is an important process in the formation of landforms and the movement of winds across the globe. In this ScienceStruck article, we will study this phenomenon, and learn about its effects on our world.

Nov 22, 2019 · A convection cell is a system in which a fluid is warmed, loses density and is forced into a region of greater density.
A convection cell is a system in which a fluid is warmed, loses density and is forced into a region of greater density. The cycle repeats and a pattern of motion forms. Convection cells in Earth's atmosphere are responsible for the blowing of wind, and can be found in a variety of other natural and manmade ...

Convection is the transfer of heat via the motion of a heated fluid. This can happen in two ways. In natural convection (or free convection), a portion of the fluid receives heat from a heat source. This raises the average kinetic energy of the molecules in that portion, which decreases its density. The heated, less dense fluid rises, and cooler, denser fluid from above sinks to replace it. (See demonstrations 36.34 -- diet vs. regular Coke, 36.36 -- Archimedes’ principle, 36.37 -- Cartesian divers or 36.39 -- helium-filled balloon). The heated fluid that has risen loses its heat to the surrounding fluid and cools, thus becoming denser. It then sinks to the bottom to be heated again and repeat the process. This type of convection occurs in the earth’s mantle and in the oceans, and in the atmosphere (the troposphere, the lowest region) it is responsible for surface winds and weather. (In the atmosphere, as the air rises it cools as a result of adiabatic expansion.) Convection also occurs in the sun, and plays an important role in ovens and the heating of rooms. In forced convection, one uses a pump or blower to push the heated air from the heat source to cooler regions.

Density differences can cause convection cells to form. Convection is a pattern of heat movement that takes place within fluids (liquids and gases). An example ...
