Amajor concern about increasing global temperatures is that a large portion of polar ice could detach melt into the ocean. if this happen which two spheres would interact

Hydrosphere and Cryosphere

Explanation:

Hydrosphere refers to the region that contains all the water bodies on earth. It covers almost 70% of the earth's surface.

Cryosphere refers to the region that is comprised of all the frozen water bodies on earth. It includes the glaciers and ice-bergs.

The increasing global temperature will lead to the melting of ice that are in the polar region. This process of melting of ice will interact with the cryosphere and the hydrosphere. Due to this melting of the ice, the glaciers and ice will be reduced drastically affecting the cryosphere. The sea level will eventually rise as a result of which the hydrosphere also will be affected.
