This document provides an overview of the water cycle and atmospheric moisture. It discusses the three states of water, the processes of evaporation, condensation, and sublimation. It describes how temperature and pressure affect the amount of water vapor air can hold. Cloud formation results from air rising and cooling, releasing water as condensation. Precipitation forms as cloud droplets grow very large. The document also discusses atmospheric stability and various mechanisms that cause air to rise and form clouds.
