GENERAL KNOWLEDGE

Detailed explanation-1: -What is the biosphere? The biosphere is the thin life-supporting stratum of Earth’s surface, extending from a few kilometres into the atmosphere to the deep-sea vents of the ocean. It is composed of living organisms and nonliving factors from which the organisms derive energy and nutrients.

Detailed explanation-2: -The biosphere is a relatively thin layer of the Earth’s surface that supports life, reaching from a few kilometers into the atmosphere to deep-sea vents. The biosphere is a global ecosystem made up of living organisms (biota) and the nonliving (abiotic) factors that provide them with energy and nutrients.

Detailed explanation-3: -The atmosphere is comprised of layers based on temperature. These layers are the troposphere, stratosphere, mesosphere and thermosphere. A further region at about 500 km above the Earth’s surface is called the exosphere.

Detailed explanation-4: -The biosphere is made of three parts, called the lithosphere, atmosphere and hydrosphere.
