WHY DOES A LUNER ECLIPSE OCCUR ONLY DURING A FULL MOON ?
The moon, earth and the sun have to lie on the same line so that a shadow would fall on the moon, allowing a lunar eclipse to occur. Without a full moon, there would be no lunar eclipse.
hmm..well if you look at it its the position the sun and the moon have together. they are moving direcly opposite from each other but they are still there
