Document Summary

Law 2: planets speed up when approaching the sun. Thermodynamically open: mass and energy flows into, through, and out of them. This external forcing sustains them in a constant state of motion, their parts ever interacting and feeding back off each other. Nested within a system of smaller systems and evolves over time. Feedback: a process operating between parts of the system. Amplify: positive feedback (volcanism increase of co2 increase temp increase water vapour) Suppresses: negative feedback (increase greenhouse increase weathering + ca to oceans decrease. Earth systems are like a story and you are trying to solve how the story occurred. Geosphere: dense, primarily solid parts of the earth that is of rock and overlying sediment. Land bridge: narrow strip of dense, felsic rock that crossed oceans have risen and sunk over time allowing animals to pass (same animal in different areas) The continents have drifted across the earth over time.
