Question

1. Suppose an ice sheet is melted enough to cause a 3.3 mm rise in sea level. Convert this 3.3 mm in kilometres.

Answer 1

To convert a mass of ice into the total amount global sea levels would rise if the ice all melted (i.e., the sea level equivalent), we need to know how much area the oceans cover. This is usually given as 3.618 x 108 km2.
