THE FULL MOON
This photograph of the moon shows clearly that the moon is round or, to say it more correctly, the moon is an almost perfect sphere. The moon does not shine by its own light as the sun does. Instead the moon shines by light reflected form the sun. The sun shines on the moon and then the moon sends the light on to use. You have probably caught sunlight in a mirror and sent it on, in just the same way.
When the moon is in such a position that the whole face sends light to us, it looks round and we call it a "full" moon. This view is of a full moon. At other times the moon is in different positions and only part of it face sends light to use. Then we say the moon is new. However the moon is a sphere all the time, whether it looks that way or not. It is made of the same material as the earth, and we know the earth could not change from a sphere to a crescent in a few days.
Children often wonder if anything lives on the moon. Nothing that is like the people, animals, and plants that we know could live there for the temperature on the moon is sometimes more than 200 (degrees) below zero. On the other hand the lack of atmosphere causes the moon's surface to become melting hot when the sun strikes it directly.
The tides of our oceans are chiefly due to the attraction of the moon on the water. High tide comes regularly, about fifty minutes later each day, just following the passing of the moon. Scientists have decided, therefore, that the attraction (drawing power) of the moon causes the tides.
Another stereograph tells you more about the moon.
