Question

the simulation indicated that if all the ice in greenland melted, the sea level would rise by about 7 m. we found that this corresponds to about 2,500,000 km³ of ice melted. how much would the sea level rise if “only” 500,000 km³ of ice melted? (you can use 7 m sea level = 2,500,000 km³ ice as a conversion factor.)

1.4 meters

5.0 meters

35 meters

2.5 meters

Explanation:

Step1: Set up proportion

Let $x$ be the sea - level rise. The proportion is $\frac{7}{2500000}=\frac{x}{500000}$.

Step2: Cross - multiply

$2500000x = 7\times500000$.

Step3: Solve for $x$

$x=\frac{7\times500000}{2500000}=\frac{3500000}{2500000}=1.4$.

Answer:

A. 1.4 meters
