Above Ground
On The Ground, The Earth's Surface
noun, の adjective
Remember 地下, which is "below ground." Well, this is ground and above combined together, so I bet you can guess that this means above ground. But usually things above ground don't float (unless you're in space), so it's really on the ground.
This is a jukugo word that uses the on'yomi readings of the kanji. You should be able to read this on your own.

地上に生まれる
