The ocean level rises when global temperature rises, due to ____________________. A) Both of these.B) Neither of these.C) melting of ice caps at the poles.D) thermal expansion of water.
Two main factors contributed to observed sea level rise. The first is thermal expansion: as ocean water warms, it expands. The second is from the contribution of land-based ice due to increased melting. The major store of water on land is found in glaciers and ice sheets.
So I don't know what C means: ICE caps. Sea ice melting has no effect on rise in sea level. Land ice, however, does.
