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.

  • physics -

    Two main factors contributed to observed sea level rise.[6] The first is thermal expansion: as ocean water warms, it expands.[7] 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.
