Question : The Sun heats the Earth through:
Option 1: conduction
Option 2: radiation
Option 3: fission
Option 4: convention
Correct Answer: radiation
Solution : The correct option is radiation.
The Sun heats the Earth through the process of radiation. Electromagnetic radiation (EMR) from the Sun includes visible light, infrared radiation, ultraviolet radiation and other energy types. Through space's vacuum, this solar radiation makes its way to Earth. A percentage of the solar radiation that reaches Earth is absorbed by the surface. The Earth's surface warms as a result of the energy absorption.
