Question

A convection cell is BEST described as _____. A.an occluded front B.a common weather pattern C.a process within an air mass D.a loop of moving air caused by temperature differences

Answer 1

A convection cell is a loop of moving air or water brought about by differences in temperature. The correct answer is D.

Answer 2

Answer:

Option (D)

Explanation:

The convection cells is a process that generates in a fluid medium due to the differences in the density and temperature. Due to the occurrence of high temperature in a region, the warm and less dense volume of air gets uplifted and rises up. As it rises up it mixes with the cold and dense air, as a result of which it becomes cold and density increases. This process takes place repeatedly in a cyclic manner forming convection cells. It represents the vertical mixing of gas or liquid.

Thus, convection cells are described as a loop of moving air mass that is formed because of the differences in their temperature.

Hence, the correct answer is option (D).
