Exploring Water's Journey into Earth's Atmosphere

Harold York, a research scientist, explains how water enters Earth's atmosphere. The atmosphere contains about 13 trillion metric tons of water, which is only a small fraction of Earth's total water. The primary sources of atmospheric water are evaporation from bodies of water and transpiration from plants. Other minor sources include sublimation and volcanic steam. The video concludes with a summary of these processes.
