Arctic sea ice has declined over the past few decades causing water levels to increase. This is an interaction of which two spheres?

Biosphere and geosphere
Cryosphere and hydrosphere
Geosphere and atmosphere
Hydrosphere and geosphere

This is an interaction of cryosphere and hydrosphere spheres.

Explanation:

The cryosphere is the sphere of the earth made up of ice sheets, icebergs, and glaciers, etc – which is mainly frozen water. When the ice melts, the melted water enters the oceans – which form part of the hydrosphere (another sphere of the earth), causing a rise in ocean surface levels.  This mainly happens when global temperatures increase causing the polar ice-sheets to recede due to melting ice. The reverse can also happen when global temperatures drop such as during ice ages.

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )
