What is a biosphere? GEOPHYSICS
Bio= • Sphere=
There is only one biosphere on Earth, and that’s Earth… • The term "biosphere" was coined by geologist Eduard Suess in 1875, which he defined as:[2] • the place on earth's surface where life dwells.
What’s so special? • A biosphere is a closed system that is self sustaining. It needs nothing replenished from the outside…it does it all, itself. • For example: the water cycle…. • Photosynthesis and Respiration…
Specific biospheres • When the word Biosphere is followed by a number, it is usually referring to a specific system or number. Thus: • Biosphere 1 - The planet Earth • Biosphere 2 - A laboratory in Arizona which contains 3.15 acres (13,000 m²) of closed ecosystem. • BIOS-3 was a closed ecosystem at the Institute of Biophysics in Krasnoyarsk, Siberia, in what was then the Soviet Union. • Biosphere J (CEEF, Closed Ecology Experiment Facilities) - An experiment in Japan.
