one
B
two
C
three
D
four
Explanation: 

Detailed explanation-1: -These four subsystems are called “spheres.” 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.

Detailed explanation-2: -The subsystems are known as “spheres.” Specifically, they are known as the geosphere (land), hydrosphere (water), biosphere (living things) and atmosphere (air). Environmentalists use this system to classify and study the organic and inorganic materials found on the Earth.

Detailed explanation-3: -We generally divide the earth into four spheres: (i) the atmosphere, (ii) the hydrosphere, (iii) the biosphere, and (iv) the lithosphere. The atmo-sphere is a thin gaseous envelope surrounding Earth. The hydrosphere is the water, primarily the oceans. The biosphere includes all living things on the planet.

Detailed explanation-4: -Within the boundary of the Earth is a collection of four interdependent parts called “spheres“: the lithosphere, hydrosphere, biosphere, and atmosphere. The spheres are so closely connected that a change in one sphere often results in a change in one or more of the other spheres.

Detailed explanation-5: -There are five main systems, or spheres, on Earth.
