Which of these is part of the geosphere?
a.

b.
a crustal rock
c.
a stream system
d.
an animal skeleton

Option (D)

Explanation:

Geosphere refers to the region where there is continuous interaction between the hydrosphere, lithosphere, atmosphere and cryosphere.

Hydrosphere includes the water bodies on earth.

Lithosphere includes the region that contains the crust, mantle, landforms and their composition.

Cryosphere refers to all the snow covered region on earth.

Atmosphere is considered to be the gaseous envelope of the earth comprised of different layers.

The skeleton of an animal does not show any interaction between the above different spheres. So it is not a part of geosphere.
