2. Craters in the Sea.
Only a handful of impact craters have ever been discovered under the
sea. One reason is that the sea floor is harder to get to and to study
than places on land. There is another reason. What is it?

3. Craters Around the Globe.
Visit a world map of impact craters at: http://gdcinfo.agg.emr.ca/crater/world_craters_e.html
Have more impact craters been discovered in some places than in others?
Where are these "clusters" of craters? Why are they where
they are and not somewhere else?

P/Shoemaker-Levy 9 in 1994. w
No craters were made by this impact. Why not?

5. Impacts Elsewhere in
the Solar System.
Would you expect to find impact craters on solid bodies in the rest
of the solar system? Why or why not?
