Question

Over the past century, the global sea level has risen by 4 to 8 inches. However, over the last 20 years this increase has been occurring at approximately twice the average speed of the preceding 80 years.

__________ is NOT a cause for this increased global sea level.
A) Thermal expansion
B) Melting of glaciers and polar ice caps
C) Ice loss from Greenland and West Antarctica
D) An increase in the water present in the water cycle

Answer 1

The correct answer is D. An increase in the water present in the water cycle.
The water is not rising and dropping in level because of a water cycle, but it depends from the position of the continents, how much water is in solid form (ice), and the rise and drop of temperatures worldwide.
