When the astronomer Galilco first looked through a telescope at the Moon in 1609, he saw that its surface was covered in mountains and craters. He could see these because they were lit up by sunlight and they had very clear shadows. Your task is to find some photographs or drawings of craters on the Moon. Study them carefully and, in the space below, sketch a typical crater and label the shadows. Draw an arrow to show the direction of the sunlight which is lighting up the crater.
