Natural Factors That Causes Climate Change Flashcards
What is the Milankovitch cycle
influences the earth’s climate by changing how much solar energy reaches the earth
Explain how precession effects climate change
•earth wobbles like a spinning top
•on a 26,000 year cycle
•some areas receive more sunlight then other areas
• fluctuates between 41.5 and 44.5
• earths water levels can change the wobble ratio by a few centimetres
• increase in sea level rise would change wobble ratio would wobble west- change the climate
How does eccentricity effect climate change
•Earth rotates on a 940 million kilometer orbit around the earth
•A complete orbit takes 365 days
• When elliptical the earth is further away of the sun so it would receive less sunlight glacial period
• when circular the earth is closer to the sun so it would receive more sunlight interglacial period
• takes 100,000 years
