GALILEAN SATELLITES - DO YOU SEE WHAT I SEE?

Directions: Select a recorder for your group. Using the pictures make observations of each satellite. Then answer the questions.

Observations:


	Callisto



	Ganymede

	

	Europa



	Io




Questions:


1.  Did you see examples of weathering or erosion of craters? Why or why not?



2.  What are the main agents of change you see modifying craters on Galilean
satellites?



3.  Are there other differences between the craters in the Jovian system, and those 

in the inner solar system? (HINT - think about temperature)
