Question

Which statement is the best example of transfer of heat energy by conduction?

• A. Heat energy is transferred from the surface soil to the rocks below.
• B. Heat energy is transferred from the Sun to the Earth.
• C. Heat energy is transferred from the top to the bottom of a lake.
• D. Heat energy is transferred from the Earth's surface to the upper atmosphere.

Answer 1

The correct option is A

Heat energy is transferred from the surface soil to the rocks below.

Conduction can be defined as the transfer of heat from one solid object to another where the objects are in contact and are at different temperatures. Here, in option A there is a conduction of heat energy from the surface soil to the rocks below. Options B and D are examples of radiation and option C is an example of convection.
