Terrestrial Cycle [Astro*Index]

A cycle on Earth. Any phenomenon which exhibits a repetitive nature with a period which is somewhat constant. Cycles have been studied and calculated for many thousands of categories, including: The population size of foxes, grasshoppers, owls, and salmon; the price of aluminum, butter, corn, eggs, and wheat; the production of coal, cotton, and steel; and such various events as earthquakes, Nile floods, sunspots, business failures, heart attacks, immigrations, war, and hemlines. No simple correlation has been shown between astrology and terrestrial cycles, but the topic is irresistible, and many astrologers claim success at using planetary cycles to predict such activities as stock market prices and the weather.
