Which sphere refers to the part of the Earth in which life exists?

The biosphere
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 rain forests and high mountaintops. Scientists describe the Earth in terms of spheres.

Which sphere is related to the geo surface of the Earth?

Everything in Earth’s system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called “spheres.” Specifically, they are the “lithosphere” (land), “hydrosphere” (water), “biosphere” (living things), and “atmosphere” (air).

Which is the first sphere of the Earth?

Illustration of the hierarchy of biological organization. The biosphere is the sphere of the earth which includes all organic, living life. Whether this life is on the earth’s surface, in the atmosphere, or below the ground, it is part of the larger biosphere system that makes up life on this planet.

What are the four major spheres of the Earth?

Specifically, they are the lithosphere (land), hydrosphere (water), biosphere (living things), and atmosphere (air). Each of these four spheres can be further divided into sub-spheres. To keep things simple in this course, there will be no distinction among the sub-spheres of any of the four major spheres.

What makes up the biosphere of the Earth?

The biosphere contains all the planet’s living things. This sphereincludes all of the microorganisms, plants, and animals of Earth.***

How is the sphere related to the other three spheres?

The sphere hugely depends on the other three spheres as follows: The hydrosphere replenishes plants and animals with water and moisture. The geosphere renders a solid surface for the plants and animals to inhabit. It also provides heat from beneath the earth.
