photochemical
Sunlight causes change
Photochemical describes chemical reactions or processes triggered by light.
Photochemical reactions drive photosynthesis in plants and the development of traditional film photography.
In environmental contexts, photochemical smog forms when sunlight acts on pollutants like nitrogen oxides and hydrocarbons: Photochemical reactions in the atmosphere produce ground-level ozone.
