The process of convection involves group of answer choices the slow upward flow of warmer material and downward flow of cooler material the trapping of charged particles in a magnetic zone water shaping deep cuts into the earth’s crust, such as the grand canyon ultraviolet rays changing regular oxygen into ozone

the slow upward flow of warmer material and downward flow of cooler material.

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.

Air pollution: “combustion results in gases such as nitrogen oxides, nitrogen dioxide and particulates. the main causes of air pollution include transport, domestic combustion and industrial processes. pollutants from these sources can cause problems in the immediate vicinity and a distance away.”
