Answer:
the slow upward flow of warmer material and downward flow of cooler material.
Step-by-step explanation:
- The process of convection starts with the movement of fluids, liquids, and gases that take place in solids, liquids and gases mediums though mostly in the atmosphere.
- As the convective currents rise from the zero degrees latitude also known as the doldrums to the polar areas and the slow flow of cold polar air from the higher altitudes towards the warmer lower latitudes below.
- Thus convections regarded as the transfer of the heat contents, it can be natural, and gravitational and thermodynamically induced also. Its seen in major weather phenomena and in the oceanic circulation also.
