EVERYDAY SCIENCE

Detailed explanation-1: -The biosphere is made up of the parts of Earth where life exists. The biosphere extends from the deepest root systems of trees, to the dark environment of ocean trenches, to lush rainforests and high mountaintops. Scientists describe Earth in terms of spheres. The solid surface layer of Earth is the lithosphere.

Detailed explanation-2: -Solution : Biosphere is the part of the earth which supports the biodiversity. The biosphere is the sum total of all the huge ecosystems found on earth.

Detailed explanation-3: -The biosphere is made of three parts, called the lithosphere, atmosphere and hydrosphere. 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. The hydrosphere is the aquatic portion of the planet, all of which supports life.

Detailed explanation-4: -What makes the Earth habitable? It is the right distance from the Sun, it is protected from harmful solar radiation by its magnetic field, it is kept warm by an insulating atmosphere, and it has the right chemical ingredients for life, including water and carbon.

Detailed explanation-5: -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.
