Which process causes earths surface to warm

B. The radiation of the sun's electromagnetic waves

Heat from the Earth's core and radiation from the Sun is transferred to the surface of the Earth by conduction.

The correct answer is option B, the radiation of Sun's electromagnetic waves

Explanation:

The temperature of earth rises due to following two physical process –  

a)The absorption of heat radiated by Sun by the earth

b)The absorbed heat of sun is radiated back by the earth to the outer universe but due to earth’s atmosphere it could not escape and thus this heat further raises the temperature of planet Earth.

consider the reaction below.
