Terrestrial
From Wikipedia, the free encyclopedia.
Terrestrial literally means 'of the earth' and is used in a variety of contexts:
- In biology, terrestrial means indicates ground-dwelling (compare aquatic). See land.
- In broadcasting terrestrial indicates that TV or radio signals are received through a conventional aerial. See terrestrial television.
- terrestrial may also be used in contrast to extra-terrestrial, indicating creatures from the earth rather than from outer space.
