What is hydrosphere-cryosphere?

Answer 1

If you combine hydrosphere, a sphere of water, with cryosphere, a cold sphere, you get a sphere of ice.

Answer 2

The hydrosphere refers to all of the water on Earth, including oceans, lakes, rivers, and groundwater. The cryosphere refers to the frozen water on Earth, such as ice caps, glaciers, and permafrost. Together, the hydrosphere and cryosphere interact to influence Earth's climate and play a key role in regulating the planet's temperature.
