PTYS/ASTR 206 – Section 2 – Spring 2007
Activity #10: 2/27/07
NAME:_________________________________________________________________
The purpose of this activity is to go over material covered both in class and in the textbook. This is an
ACTIVITY, so feel free to discuss these with one or two of your neighbors. You must turn in your
own work.
You decide how much the question is worth! You can choose each number (4, 3, 2, 1) only once.
The total must equal 10 pts. Circle the value you wish for each question. If you do not wish to use this
system of scoring, the values underlined will be used (don’t circle anything in this case).
#1. 4 pts 3 pts 2 pts 1 pt Explain the difference between Earth’s emitted radiation, and
reflected solar radiation. At what part of the electromagnetic spectrum is the spectrum of each of these a
maximum?
#2. 4 pts 3 pts 2 pts 1 pt A common misconception is that the ozone hole has something to do
with the greenhouse effect. Based on what you heard in today’s lecture, explain why the ozone hole has
nothing to do with the greenhouse effect.
#3. 4 pts 3 pts 2 pts 1 pt Which statement is true about the asthenosphere and lithosphere of
Earth? (circle one and give a very brief answer to the question at the end)
A) The asthenosphere and lithosphere are layers in Earth’s upper atmosphere
B) The asthenosphere is another name for Earth’s outer crust, and the lithosphere is the
upper part of the Earth’s mantle
C) The asthenosphere is the fluid-like upper part of Earth’s mantle, and the lithosphere is
the solid crust that rides on top of it
D) The asthenosphere is the region outside of Earth’s magnetopause where solar wind is
diverted around Earth, and the lithosphere is the region inside the magnetopause
containing the Van-Allen radiation belts.
What is the source of energy that drives the motions in these parts of Earth?
(over for 1 more question)
#4. 4 pts 3 pts 2 pts 1 pt What is the origin of aurora? Why do they appear primarily at high
northerly and southerly latitudes (as opposed to near the equator)?
