Try to make inferences (guesses) about the features and planets based on your observations. In your journal, list the image number, describe what you see, and tell what you think the image shows. Skip about six lines after your description of each image for Part II of this assignment. There are many dark, circular areas of different sizes on the surface. The sides around the craters seem to be higher and brighter than the dark center.
