... The zone where life is found; the outer portion of the geosphere and the inner portion of the atmosphere . This extends from 3 m below the ground to some 30 m above it. The biosphere also comprises that region of waters, some 200 m deep, where most marine and freshwater life is found. Gaia theory postulates biosphere-scale evolution; Free and Barton (2007) Trends in Ecol. & Evol. 22, 11 ask whether and why the biosphere might tend towards stability and self-regulation (but don’t look for a clear-cut answer). See Phillips (2008) PPG 32, 1 ...

... The biosphere is the part of our planet that is inhabited by life. It consists of three zones: the lithosphere , comprising the Earth's crust, together with accumulated soils and sediments; the hydrosphere , that part of the lithosphere covered in water, including groundwater; and the atmosphere , the gaseous envelope surrounding the Earth. Life on Earth is extremely ancient, having evolved before 3.8 billion years (Ga) ago. It has played, and still plays, a major role in the development of our planet and its climate. The greatest biomass, and...

... The regions of the Earth inhabited by organisms and the totality of life on Earth are known collectively as the biosphere . The term is sometimes restricted to denote only the living biota (plants, animals, and microorganisms) on the planet and was first used formally by the geologist Eduard Suess in 1875 . However, in the decades that followed, Russian writers developed the concept of the biosphere. The term has become increasingly familiar in the early twenty‐first century, with the development of studies of ecological systems and concern over...

... ( ecosphere ) The part of the Earth in which living organisms exist and interact, which includes the atmosphere , hydrosphere , and lithosphere ; the sum of all ecosystems . The biosphere extends from less than 11 km below sea level , to the tropopause which is less than 17 km above sea level. This gives it a maximum thickness of 38 km—roughly 0.5% of the radius of the Earth (6371 km). The concept of the biosphere as the Earth's integrated living and life‐supporting system was first proposed in the 1920s, but only in recent decades has it been...
