Earths 41000 year cycle
Webow many precession periods (26,000 years) are in one cycle of Earth's orbit eccentricity period (100,000 years)? How many orbit eccentricity periods did the Earth go through in the last 410,000 years? This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. See Answer The 100,000-year problem (also 100 ky problem or 100 ka problem) of the Milankovitch theory of orbital forcing refers to a discrepancy between the reconstructed geologic temperature record and the reconstructed amount of incoming solar radiation, or insolation over the past 800,000 years. Due to variations in the Earth's orbit, the amount of insolation varies with periods of a…
