Answer:
C. Geosphere
★★★
Step-by-step explanation:
First, eliminate your incorrect answer choices.
The atmosphere is the air we breathe. In the atmosphere, there are clouds, airplanes, and birds, [if that makes it easier to visualize for you.]
There won't be rocks in the atmosphere [sky], so option A can be eliminated.
Now, look at B.
The biosphere is living things around us. For example, trees, plants, animals, even humans, are apart of the biosphere.
Rocks aren't living beings, so they cannot be apart of the biosphere [living beings/things]. So option B can be eliminated.
Next, look at C.
The geosphere are things apart of earth that aren't living. What I mean is caves, mountains, and rocks.
Rocks are definetely apart of the geosphere, so option C is correct.
Finally, look at D.
The hydrosphere is everything water. Its in the name itself, "hydrosphere," meaning "water-sphere."
[Don't get this confused with ice. Glaciers, snow, and ice are apart of the cryosphere, which is everything ice.]
Rocks are not apart of the hydrosphere since they have nothing to do with water. So option D can be eliminated.
So, the final answer is C. Geosphere.
