Document Summary

: the sun -it has changed its magnitude over its lifespan, it has increased by 10% and initially 75% as strong as it is now. The orbit of the earth around the sun - if the solar system was just the earth and the sun it would be a perfect ellipse, however since there are more planets so the orbit of earth can change. Example the tilt of the earth can change in. Location of the continents- continents have shifted, high latitude ice sheets aren"t possible, mountain ranges. Volcanoes- shot timescales cause cooling, over long time scales they add co2. Proxy data: tells us about temperature, precipitation, etc. through other indicators. Ice core data- ice at the bottom of greenland and antarctica is over 100,000 years old. Ice can have tiny bubbles which can tell us about the atmosphere. Geological data: sediments, shape of the land etc. Glaciers cut out land in the seattle area from glacier flows.
