The planet Earth is a very special place. Earth Mysteries Revealed explains how our planet is put together and answers the questions to mysteries such as: why is the only life we know of found on Earth; how did this warm and wet planet form from a cloud of ice and dust; was the Moon once a part of Earth's rocks; why is it night all winter in the Arctic; why are sunsets orange; and was there really an ancient city that was destroyed by a volcano and tsunami?
