Document Summary
Nature climate: climate is influenced by 5 components: atmosphere / oceans / cryosphere / biosphere/ lithosphere. Atmosphere o o change overtime, different level of oxygen (bacteria) Solar energy o sunspots: region on the sun"s surface with lower temperature than its surroundings and intense magnetic activities affect energy reaching to. Earth more sunspots = more energy reaching the earth. Definition: a set of cyclic variables (in milankovitch theory) in the characteristics of the earth"s orbit around the sun, which cause changes in the amount and distribution of solar radiation reaching the earth"s surface, firstly discussed by a. Three orbital parameters are especially important in causing ice-sheet waxing and waning: o. Eccentricity: the shape of the earth"s orbit around the sun. As the axial tilt increases, the seasonal contrast increases. The seasons become exaggerated, more tilt means more sever seasons and less tilt means less severe seasons.
