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.

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.
