MAHARASHTRA Class 9 - Biogeochemical Cycles Videos

The biosphere is the outermost part of the planet which includes air, land, surface rocks and water.

The cyclic flow of nutrients between biotic and abiotic components is called a biogeochemical cycle.

Evaporation is followed by condensation, which is the process by which water vapour is changed back into liquid water.

Precipitation is the term for the falling of condensed water molecules in the form of rainfall.
