47. Consider this blog about the recent big Chilean Earthquake: http://blogs.agu.org/tremblingearth/2015/09/24/chile-‐ keeps-‐having-‐earthquakes/ Why were there so few deaths?
a. it was very rural with low population
b. the earthquake was 100’s of km deep, and thus the energy was less by the time it reached the surface
c. the earthquake was off shore, so the shaking was not as severe
d. it was a strike slip earthquake, and thus did not produce a damaging tsunami
e. all of their buildings are built with a rigorous seismic safety code, and hence did not collapse
48. Read this short blog about global temperatures in September 2015: http://blogs.agu.org/wildwildscience/2015/10/21/september-‐ global-‐heat-‐record-‐smashed-‐2015-‐will-‐almost-‐ certainly-‐pass-‐2014-‐as-‐hottest-‐on-‐record/
Why is this article stressing the importance of the recent “warmest month” record?
a. because September is not particularly known for being a hottest month
b. because there is no more snow-‐covered peaks in the Appalachians, which hasn’t happened for 100,000 years
c. because of the magnitude that the record was broken: it was broken by a large amount
d. for the first time, politicians have finally accepted it was a warmer month than usual
e. answers a and d
49. Read this short note about CubeSats: https://eos.org/articles/u-‐s-‐launches-‐13-‐new-‐minisatellites
By the way, many of these are being developed at ASU. Why is there a growing trend towards CubeSats?
a. they are compact and relatively light, and thus easier to get to space
b. they are less expensive than traditional satellites
c. with cubic symmetry, they take advantage our nerd nature to put everything into a box. Yay!
d. they can accomplish more tasks that larger platform satellites
e. answers a and b
50. Last but not least, life in our Solar System… Read this short news item and select the answer below which is most consistent with something mentioned in the article.
https://eos.org/articles/astrobiology-‐hearing-‐ranges-‐beyond-‐life-‐as-‐we-‐know-‐it
a. While life may exist elsewhere in the Universe, it is only on Earth in our Solar System.
b. There are a number of candidate locations in our Solar System where we might find life.
c. With all the advances in human genome sequencing, we understand what life to expect, if we find it.
d. NASA Chief Scientist Ellen Stofan discussed how life can exist in Martian briney waters.
e. The most likely non-‐Earth place to find living organisms is in the ice and water in our Moon’s polar craters.
