GGR100H1 Lecture Notes - Lecture 2: Negative Feedback, Hydrosphere, If And Only If
Document Summary
Ordered interrelated set of things and their attributes. Either store or output material and energy in addition to intake. All (except earth tectonics) stem for solar energy. There are both open and closed systems, although most systems in nature are ipen - both input and output, for example solar energy reachi ng earth and bing goiven off as heat energy. Things as small as a single leaf can be considered a suystem - sunlihht, co2, giving off water and oxygen. Systems can also be closed- earth, including the atmosphere, in terms of matter- water, elelments, is mostly a closed system, other than things like meteors, although in terms of energy the earth is an open system. Systejm feedback-outputs form the system loop aorund and become an input at a later ppoint and influence its own operations.
