Biogeochemicals are essential elements or nutrients (H ₂O, N, O, C, etc.) required by living organisms which are obtained from Earth (land, air and water).

Biogeochemical cycles are repeated circulation of biogeochemicals between abiotic and biotic components of the environment which result in their repeated withdrawal and replacement of their pool.

Methane burp is a process of periodical release or belching of methane in huge quantities. This is caused by the melting of the methane hydrates existing in permafrost and sea floor. Methane is a GHG, one of the main culprit of global warming.

Wind breaks are a few rows of trees and shrubs planted on border of the crop fields at right angles to the direction of wind. This technique remains effective in checking of soil erosion by the wind.

Top soil is the upper fertile biologically active layer of soil which is rich in minerals, organic matter, microorganisms (bacteria, fungi, earthworms and other animals). Roots of plants are mostly restricted to top soil.

How do marine organisms receive continuous supply of nutrients?
Marine organisms receive continuous supply of nutrients by rivers which bring the same from rocks and soils over which water flows.
