Biosphere

Coined in 1875 by Eduard Suess, the biosphere is that part of a planet’s outer shell—including air, land, and water—within which life occurs, and which biotic processes alter or transform. From the broadest geophysiological point of view, the biosphere is the global ecological system integrating all living beings and their relationships, including their interaction with the elements of the lithosphere (rocks), hydrosphere (water), and atmosphere (air).
