Question

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

Explanation:

Polar ice is part of the cryosphere, which encompasses all frozen water on Earth. The ocean is part of the hydrosphere, which includes all liquid water on the planet. When polar ice melts into the ocean, the cryosphere (ice) interacts directly with the hydrosphere (ocean).

Answer:

○ cryosphere and hydrosphere
