Amajor concern about increasing global temperatures is that a large portion of polar ice could detach and melt into the ocean. if this happened, which two spheres would interact? a. geosphere and atmosphere b. cryosphere and biosphere c. hydrosphere and atmosphere d. cryosphere and hydrosphere

The correct answer is D. Cryosphere and hydrosphere.

Explanation

The Cryosphere refers to the parts of solid-state water on the earth's surface, including glaciers, ice sheets, frozen terrain, ice in lakes, rivers, and seas, among others. On the other hand, the hydrosphere refers to the layer of land composed of water mainly in a liquid state, including oceans, seas, rivers, lakes, lagoons, among others. According to the above, if a glacial falls off and falls into seawater to melt there, the layers of the earth that are interacting are the hydrosphere and the cryosphere. So the correct answer is D. Cryosphere and hydrosphere.
