Explanation:
The three process are as follows -
1. Reflection - part of the solar radiation will reflect back to space by gas molecules, aerosols, clouds etc .
2. Scattering - sunlight can be scattered by water vapor dust particles and gas molecules according to their size compared to the wavelength. the sky appears blue due to the scattering .
3. Absorption - some of the solar energy gets absorbed by the gas molecules, Ozone molecules can absorb high energy ultraviolet .
