Document Summary

Figure 1. 1 how the spheres come together, interact, and intercept earth system science book. Soil as lens with what is happening with earth"s larger system. Look at larger earth system and how life regulates that system. Us as organism on planet having an influence on how earth system works. Atmospheric analysis: to determine whether life was at a particular place. Life being this geologic force that shapes what happens on this planet. Earth"s anomaly: oxygen makes up 20% of the atmosphere. Oxygen is something that is rare unless u have plants and photosynthesis plants play a significant role in life. As the sun brightened, co2 was counteracting the intensity of the sun kept earth cool. Life was regulating the co2 & o2 (gases) Life and non living environ (abiotic and biotic stuff like soil) form a self regulating system that maintains a habitable state. Earth as a system is more than the sum of its parts.
