Question

. Which mode of heat transfer is used when the sun is heating the Earth’s land and water? Choose one.

a. Conduction
b. Convection
c. Radiation

Answer 1

c. Radiation

Step-by-step explanation:

The mode of heat transfer used when the sun is heating the Earth’s land and water is c. Radiation. This is because radiation is the transfer of energy by electromagnetic waves, which can travel through the vacuum of space. Conduction and convection, on the other hand, require a medium (like a solid, liquid, or gas) to transfer heat.

Answer: C

Step-by-step explanation:

When the sun heats the Earth's land and water, the mode of heat transfer used is radiation. The sun emits electromagnetic waves, including heat energy, which travel through space and reach the Earth, warming the land and water.
