Chapter 1

3. How do you think the principle of uniformitarianism accounts for occasional catastrophic events such as meteorite impacts, huge volcanic eruptions, or great earthquakes?

The principle of uniformitarianism states the processes occurring on Earth today are very similar in manner as those throughout much of geologic times. In other words “the present is the key to the past.”(Murck, B. W., Skinner, B. J., & Mackenzie, D. (2010)). When looking at past geological events and occurrences that happened in the past with additions of new testing and technology they can predict when and if volcanic eruptions may occur, meteorite impacts and their damages, and if plate shifts will occur resulting in earthquakes. Scientists rate the earthquakes on a scale based on how damaging they are.
4. In this chapter we have suggested that Earth is a close approximation of a natural closed system, and we have hinted at some of the ways that living in a closed system affects each of us. Can you think of some other ways?

Another way that living in a closed system affects us is through global warming. The fact that a closed system is by definition the concept that leads to the principle that the relationships between its basic parts are limited, and therefore changes in one part of the system are liable to produce effects in another part. Therefore, by our constant changes to the earth environment affects the human quality of life. Global warming, the cutting down of our trees and using up of all our natural resources affects our ecosystem. Thus affecting the quality of oxygen in the atmosphere changes in the weather pattern and changes in the temperature. Every aspect of our lives are within a closed system is in interdependent on one another.
