terrestrial
What does "terrestrial" mean?
The term "terrestrial" refers to anything related to the Earth or to land, as opposed to the sea or the air. Mentally, visualize the solid ground beneath your feet—the soil, the mountains, and the forests—distinct from the vast, fluid oceans or the infinite expanse of space. In common usage, it is often employed in scientific or academic contexts, such as distinguishing between terrestrial animals (those living on land) and aquatic ones. You might also hear it in broadcasting, where "terrestrial television" refers to traditional signals transmitted from ground-based towers rather than through satellites.
