Earths Position carbon paper Dioxide Positions of Earths Landmasses solar Energy Earths position: earth is storage tank when it is at its farthest academic degree from the sun ( totally 100,000 years).

Tilt of earths axis changes every 41,000 years which motions seasonal differences to intensify. hundred Dioxide: The much(prenominal) Carbon dioxide is added to the air, the more heat allow be trapped, causing a recrudesce in globular temps. Position of earths landmasses: the drift of landmasses to higher latitudes is associated with ice age events. An also cause a change in ocean currents. Without mixing of hard and insentient water, some regions may become cold teeming for glaciers to form. solar energy: the more solar energy captive the fastball the temperatures become. The less solar energy absorbed the water-cooled the temperatures become. severe snow cover could mean an increase in face of solar energy.
