Convection and conduction are affected by paving over a grass field because:
- They engage in heat transfer with the grass field as the surface contact point.
We should recall that convection is the method of heat/energy transfer where energy moves from one surface to another through movement of liquid or fluid.
On the other hand, conduction is the method of heat transfer where there is the transference of energy as a result of direct contact between a surface and the origin of the heat.
With this in mind, we can see that if there is heat transfer through either convection or conduction over a grass field then there would be some energy lost and some energy gained.
