1(1).jpg1(2).jpg2(1).jpg2(2).jpgA) Identify the three 'knobs' for the climate system - i.e. what are the three aspects of the climate system that when their values change will cause the long-term climate change. For each knob, provide a physical/chemical component or interaction within the Earth System (or Solar System) that can 'turn the knob' (i.e., change its value).4(2).jpg3(1).jpg3(2).jpg

Use the geologic sketch below to discuss the relative age of rocks and events. (note: on the exam you will see a different figure!) Figure 1: Geologic cross section. Assume that all layers are sedimentary except for C, which is
igneous, and D, which is metamorphic. A) Order the sequence of geologic events in Figure 1, from oldest on the bottom to youngest on
top. Also, identify the geologic principles you applied to make the determination. (12 points)

EAES 101: Global Environmental Change Spring 2018 B) Define what an unCOnformity is, and identify one way you may be able to determine whether
you are looking at one when you are out in the field. (4 points) C) Circle on Figure 1 an example of an unconformity, and identifl which of the three types
uneonformities it is. (4 points)

EAES 101 : Global Environmental Change Spring 2018 Possible Short Answer Question 2: (20 points total)
Think about geologic time, it’s terminology, and key events! (note: on the exam you will see a different list of geologic time units!) Geologic Time Units: Practice 1: Practice 2:
Cambrian Cretaceous
Holocene Hadean
Mesozoic Paleozoic
Permian Pleistocene
Proterozoic Triassic A) For the five geologic time units above, list them vertically from oldest (on the bottom) to
youngest (on the top). (5 points) B) For each geologic unit, identify if it’s an Eon, Era, Period, or Epoch. (5 points)

EAES 101: Global Environmental Change Spring 2018 C) For each geologic time unit above, identify one key event that occurred during it. It could be
an atmospheric development, hydrospheric development, biospheric development,
tectonic/ geographic development, etc. (10 points)

EAES 101: Global Environmental Change Spring 2018 C) From the list below, choose one long-term climate change event AND one short-term climate
change event. For each event, briefly describe the event, noting if it is a long-term or
short—term climate change event, identifying roughly when it occurred (in absolute time), and
noting some of the defining characteristics. Additionally, identify the driving mechanism(s) of
the climate change event. In many cases, the magnitude of climate change was increased by
associated feedbacks. Make sure to identifl any of the key feedbacks for that event. (10 points total - 5 points for each event) List of Past Climate Change Events: Cenozoic Cooling Little Ice Age Neoproterozoic Snowball Earth
Paleocene~Eoeene Thermal Maximum
Quaternary Glacial-Interglacial Cycles

EAES 101: Global Environmental Change Spring 2018 C) Identify the three avenues (sometimes deemed climate change policies) through which we
can try to address and/or reduce the adverse impacts fiom anthropogenic climate change. For
each avenue, provide an example of an action that can be taken by individuals or through
governments. (6 points) D) For your two adverse consequences in B), identify and discuss a climate change policy
avenue that could be implemented to address each. Make sure that you provide an explicit
example of an implementation of that avenue. Also, you must use a different avenue for each of your two conseguences. (4 points)
