Lightning Produces Nitrates

In this video excerpt from NOVA: “Earth From Space,” learn about the global impact of lightning and how it produces an essential nutrient for living things. Satellite images show the distribution of electrical storms on Earth and the frequency of lightning strikes. Visualizations and narration describe the formation of lightning and its role in the production of nitrate, a vital nutrient for life. This video also explains how rain transports nitrate to the ground, where it is absorbed by plants and becomes a part of the food chain.
