Respuesta :
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.
