Earth (disambiguation)

 * The earth or simply, earth (always written in the lower case), is a common noun which may refer to the dry surface, land, ground, or underground (Some soft earth is full of rich soil) or as a synonym for "world" (I've been all over the earth).  Narnian gnomes living within the ground were therefore called "Earthmen".
