This is a NASA 'Our World' video clip focusing on how Moon rocks brought back to Earth by astronauts have helped scientists understand more about how the main rock types of the moon differ from those on Earth. The human narrator is accompanied by a cartoon character, and rocks dressed as puppets. The role of the rock cycle in forming different types of Earth rocks is explored in some animated scenes, and the origins of the three main Moon rock types are explained. Based on this understanding scientists can piece together the geological history of the Moon. The NASA eClip is on YouTube and runs for 4 mins 09 secs.
