Figure 12. A pretend geologic cross section. Different colors/patterns represent different rock layers.   The drawing above is a geologic cross section showing the stratigraphy of an area. Place the events in order.

Study the plots below and answer the following questions.   As an aside, you can find these plots as well as daily measurements by searching for “Keeling Curve” and looking at the record maintained by the Scripps Institute of Oceanography   Figure 20. Two years of atmospheric CO2 measurements at Mauna Loa station (Mauna Kea measurements filled in in blue while Mauna Loa was offline).   Figure 21. The full record of atmospheric CO2 measurements at Mauna Loa station (Mauna Kea measurements filled in in blue while Mauna Loa was offline).   Figure 22. 800,000 years of atmospheric CO2 measurements. Measurements prior to 1958 are from ice core records. Measurements after 1958 are direct measurements from Mauna Loa Observatory.     For how much of the past two years (24 months) was the concentration of atmospheric CO2 measured at the Mauna Loa station above 400 ppm (parts per million in the atmosphere)?

What type of volcano would have produced the sequence of deposits you analyzed from Figure 13?   Hint: What type of magma (felsic vs. mafic) drives the formation of these different volcanoes?

When you are attending an interview, what six items do you need to remember to impress the future employer. 1. 2. 3. 4. 5. 6. 

What document should be presented to your employer at least two weeks ahead of time when you decide to leave a position? __________________________  ________________. What three separate areas should you communicate to your employer in this document? 1. 2. 3. 

Whether you have specific career goals or not, you can effectively plan your search for a full-time job.  

Which plate’s crust has more felsic rock?

*Bonus* What kind of fault is the feature labeled I in Figure 12? Hint: the right side of the fault is pushed up relative to the left.

Using the seismic wave arrival plot above, determine the distance each station sits from the epicenter.   Figure 6. Seismic wave arrival time plot.  

On the y axis in Figure 24, zero is set as the 1901-1960 (historical) average. In the past two decades (2000-2020) how many years had observed annual average temperatures above the historical average?
