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.)
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.)
Solution
To solve this problem, we can set up a proportion using the given conversion factor.
The conversion factor is 7 meters of sea level rise for every 2,500,000 km³ of ice melted.
So, we can set up the proportion as follows:
7 m / 2,500,000 km³ = x m / 500,000 km³
Here, x is the amount of sea level rise we're trying to find.
To solve for x, we can cross-multiply:
7 m * 500,000 km³ = x m * 2,500,000 km³
This simplifies to:
3,500,000 mkm³ = 2,500,000x mkm³
Finally, divide both sides by 2,500,000 to solve for x:
x = 3,500,000 m*km³ / 2,500,000 km³
x = 1.4 m
So, if 500,000 km³ of ice melted, the sea level would rise by about 1.4 meters.
