Week 1 Review Questions
Ch. 1 Questions
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 present is the key to the past (Murck, B. W., Skinner, B. J., Mackenzie, D., Visualizing Geology 2008). This means that anything that happens or will happen today, most likely has happened in the past. Scottish geologist James Hutton’s observation is that the physical process occurring on Earth have not changed, but the physical conditions have.

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?
A closed system is one that does not let any matter in or out, but has the ability to let energy such as sunlight in. Should matter or energy cross the sphere from the open systems just outside of Earth, changes inside the system will occur, which will cause physical changes to Earths closed system. http://www.ametsoc.org/amsedu/online/climateinfo/samplecourse/CCS01.pdf 5.) In what ways do geologic processes affect your daily life?
Geological process affect our everyday life in that everything that we see or touch has some form of minerals in them. Our laptops, tablets, televisions all have minerals in them. These minerals are known as “rare Earth minerals”. Our homes need to have the best materials to ensure safety, so the hardest rocks or minerals are used. Even things that one normally would not think contains minerals, such as toothpaste and facial care products. http://geology.com/articles/rare-earth-elements/ http://geology.com/rocks/diatomite.shtml
