GEOLOGY 110 EXAM 2 STUDY SHEET Define the following and consider how they relate to this section of the course: galaxy nebula sporangium sporophyte gametophyte megasporangium haploid diploid You will need to know the Geologic Timescale – down to the periods (Cam-Perm and Tr- K). Be able to correlate major events (first fish, first amphibians, first plants, major extinctions, etc.) with which period they occurred in. The best way to do this is to make a large timescale for yourself and fill in any important dates (cyanobacteria, oxygen in atmosphere, first eukaryotes, Ediacaran fauna, etc.) along with evolution and extinction events. 10/9 * Put the following in order of greatest to least amount of density: earth, water, earth’s surface rocks. Why are these densities important in terms of determining what the earth’s interior is composed of? How do we know that the earth’s core is made of iron? * What are the earth’s inner layers? * What are the names of the 4 inner planets? As a group, what are they called? What makes them similar/different from each other? * What makes Mercury and the earth’s moon similar and why is this important in terms of reconstructing our solar system’s early history? * What space mass separates the 4 inner and 4 outer planets? Why is it here? * What are the names of the 4 outer planets? As a group, what are they called? What makes them similar to each other? * Why was Pluto demoted from it planetary status? * What is the “good” evidence that tells us our solar system likely came into being as one entity? * What is the name of our galaxy? * Know the stellar life cycle. At which stage do stars form? How did the sun begin to shine? 10/11 T/F The early earth differentiated into its mantel and core very slowly. * Why do we have seasons on the earth? T/F The earth’s moon is further away from the earth than it was one billion years ago.

* When did large meteorite impacts on earth finally subside? What did this allow to happen on earth? * How old are the earliest fossils? What are they? * What was the early earth’s atmosphere made of? What gave it this atmosphere? * Why does earth have an ozone today but did not during its very early history? * What was the “organic soup?” What created the contents of it? * What was the Miller Experiment (1953) and why was it so important?
