Assignment 6 (Craters)


Assignment 6 - Craters

A closer look at some craters...
10) Is there a difference in the appearance of the inside floor of a crater and the ground surrounding
the crater?

Dion on the left The Moon on the right

Both of the above craters were selected for their similarity in size (About 60 Km across) and for their position with respect to the terminator so that lighting conditions were constant. The floors of these craters are markedly different Dione’s being rough and granular whereas the Moon is much smoother. On the outside of the Dione crater little deformity of the surrounding surface from the crater’s formation can be seen. On the Moon however surface disruption is evident at the 7 and 9 o’clock positions. Along the eastern edge the ground seems to rise appreciably towards the crater rim.

11) From what you know or suspect about the way impact craters form, would you expect there to be a difference? Why?

There are many considerations that need to be taken into account when examining a crater. I have listed some of them with their implications. Impacted body mass. Large mass bodies like our Moon have a higher gravity which causes higher energy impacts. More massive bodies are more likely to retain ejector from the crater
formation.
