Question

define physical factors of above biosphere

Answer 1

The biosphere is the portion of Earth where life occurs -- the portions of the land, water and air that hold life. These parts are known, respectively, as the lithosphere, hydrosphere and atmosphere. The lithosphere is the land mass, excluding Earth’s mantle and core, which do not support life. The hydrosphere is the aquatic portion of the planet, all of which supports life. The atmosphere is the air that living organisms use for respiration, and which supports life up to 2,000 meters above the planet’s surface.
