Answer:
Conduction is the transfer of thermal energy through direct contact. Convection is the transfer of thermal energy through the movement of a liquid or gas. Radiation is the transfer of thermal energy through thermal emission.
A-Locations M and O are at the poles.
Explanation:
Locations M and O are located at the poles because they receive sunlight that is spread out over a large surface area. The poles receive sunlight at an angle to the surface and it causes the rays of the sun to spread out in all direction.
- At the equator, sunlight impinges directly on the surface and the solar radiation here is very much.
- It is important to know that the sun is overhead directly at the equator.
- The earth is tilted at an angle to sun and therefore, areas around the polar region will receive sunlight that is spread out in different directions over a large area.
- Away from the pole, the equator is directly facing the sun and it receives direct sunlight.
