Heat energy produced by sun reaches to earth due to ___________.

Correct option is C

The correct answer is (c) radiation.

How Heat Energy from the Sun Reaches Earth:

• Radiation is the transfer of energy in the form of electromagnetic waves, such as light and infrared rays.
• Heat from the Sun travels through the vacuum of space via radiation, as there is no medium (like air or water) in space for conduction or convection to occur.
• This process allows the Sun’s energy to reach Earth, warming the planet and enabling life.

Additional Information:

• Conduction:

  • Heat transfer through direct contact of particles in a solid or between solids.
  • Example: Heat traveling through a metal rod.

• Convection:

  • Heat transfer through the movement of fluids (liquids or gases).
  • Example: Boiling water, where hot water rises, and cooler water sinks.

• Air:

  • While air can act as a medium for heat transfer via convection, it is not a mode of heat transfer in itself.
