Definition of biosphere
- According to Vladimir Vernadsky, Biosphere is a self-regulating system, including living components as well as non-living components.
- Biosphere is a specific envelope of the Earth system, comprising all living organisms on Earth, and all parts of Earth where life exists, from bottom of the ocean to the upper atmosphere.
The biosphere is 10 km deep within the ocean, and up to 10 km above the sea level. The Biosphere is approximately 20 km thick, which is very thin compared to other spheres of the earth system. Earth is the only planet where biosphere existence has been found. So, the biosphere is a unique layer.
