Answer:
Convection is equal to the conduction plus fluid flow.
Explanation:
Convection is a mode of heat transfer that requires the movement of the molecules of the medium from one point to another. It takes place majorly in fluids (liquids and gases). While conduction is a process by which heat is transfered by the vibtation of molecules of a medium at their possitions, thereby colliding with other neighbouring molecules to transmit heat.
Before convection could occur, there must be conduction of heat by the molecules of the medium which causes their motion. According to the kinetic molecular theory, any molecule of the medium close to the source of heat conducts heat, becomes less dense and thus moves so that its initial position would be occupied by another denser molecule. This continous process generate convection or convectional current. Therefore, convection is as a result of conduction and fluid flow because a molecule must first conduct heat before it moves.
<span>The planet which shows evidence of water erosion is Mars. Scientists discovered that Mars is the only other planet which has evidences of water existance as Mars' atmosphere contains trace amounts of water vapor, and it surprisingly turned out that it also has polar ice caps which are filled with frozen H2O. And, as you may have heart, Mars has shown many evidences of past river valleys and lakes.</span>
