The document discusses the Milankovitch Theory of Climatic Change, which proposes that variations in Earth's orbit and axis affect the amount of solar energy received in different latitudes and seasons, resulting in ice ages and interglacial periods over long time scales of around 40,000 to 100,000 years. The theory was proposed by Serbian scientist Milutin Milankovitch in the 1920s and suggests that changes in the Earth's position relative to the sun can impact global climate by altering the intensity and distribution of sunlight reaching the Earth's surface. The Milankovitch cycles of eccentricity, axial tilt, and precession are seen as the primary orbital
