Answer: reflected, clouds, greenhouse effect.
Explanation:
Sunlight can be absorbed, reflected , or scattered before it reaches Earth’s surface. About 30 percent of sunlight hits Earth directly, and 22 percent is filtered through clouds . Dust particles scatter short wavelengths, which causes the sky to appear blue. Earth radiates heat into the atmosphere, which traps the heat in gases, causing the greenhouse effect.
According to the context, the missing words to correctly complete the paragraph are the following:
Sunlight can be reflected or scattered before it reaches Earth's surface. About 30 percent of sunlight hits Earth directly, and 22 percent is filtered through clouds. Dust particles scatter short wavelengths, which causes the sky to appear blue. Earth radiates heat into the atmosphere, which traps the heat in gases, causing the greenhouse effect.
The Sun is the main source of energy for all the processes that occur in the earth - atmosphere - ocean system.
Sunlight passing through the atmosphere undergoes a weakening process due to scattering (due to aerosols), reflection by clouds and absorption by gas molecules and suspended particles.
Consequently, gases in the atmosphere that absorb infrared radiation from the Earth or outgoing radiation are known as greenhouse gases.
Therefore, we can conclude that sunlight passing through the atmosphere undergoes a weakening process due to scattering, reflection by clouds and absorption.
