Question 4

The correct answer is b.
The sea level rise is due to the melt of continental ice (glaciers). Iceberg, as an ice cube in a glass, present a larger part below sea level than above. Moreover ice takes a larger place than water. Consequently, when an iceberg melt, sea level don’t move. When glaciers melt, this inland water by runoff is added to marine waters causing the rise of seawater level. Rains come from the evaporation of waters and don’t impact sea water level.
