What is Photosynthesis

The complex chemistry and basic physics of Earth's atmosphere will be reduced to three main sections within the context of the chemical reactivities of predominant chemical species and the additional role of photochemistry from solar radiation. The three areas of chemical interactions and photochemical reactions in the atmosphere discussed are (1) the reactivities and relationships between chemical species that can affect tropospheric and stratospheric ozone concentrations, (2) reactions between chemical species that create acid rain, and (3) the chemical species, sources, and reactions that are believed to be contributing to climate change. These three areas in atmospheric dynamics will comprise this chapter along with some of the documented effects on ecological systems, human health, and infrastructure.
