Question

which sphere in the earth system is also part of the hydrosphere?
a. atmosphere
b. biosphere
c. cryosphere
d. geosphere

Explanation:

The hydrosphere includes all water on Earth. The cryosphere consists of frozen water (like ice caps, glaciers, sea ice), which is a form of water, so it's part of the hydrosphere. The atmosphere (gases), biosphere (living things), and geosphere (solid Earth) are not primarily water - based like the cryosphere.

Answer:

C. Cryosphere
