A major 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? question 18 options: 1) cryosphere and hydrosphere 2) hydrosphere and atmosphere 3) geosphere and atmosphere 4) cryosphere and biosphere

If the large portion of polar ice detached and melted into the ocean due to increasing global temperatures, the two spheres that would interact would be the cryosphere and hydrosphere. All of the choices would interact but the most closely related to melting would be the hydrosphere and it would affect ocean current circulation patterns and sea level.
