Ablack sand beach would be considered part of which sphere?
a. geosphere
b. cryosphere
c. hydrosphere

It'd be considered a part of the geosphere.

Here's all of their definitions though:

Geosphere: any of the almost spherical concentric regions of matter that make up the earth and its atmosphere, as the lithosphere and hydrosphere.

Cryosphere: The cryosphere is the frozen water part of the Earth system.

Hydrosphere: all the waters on the earth's surface, such as lakes and seas, and sometimes including water over the earth's surface, such as clouds

Biosphere: the regions of the surface, atmosphere, and hydrosphere of the earth (or analogous parts of other planets) occupied by living organisms.

Probably the hydrosphere altough I'm not positive
