Final answer:
To find the difference in elevation between the Dead Sea and Athens, you add the absolute values of their elevations, which are 420 meters below sea level and 45 meters above sea level, respectively, resulting in a difference of 465 meters.
Step-by-step explanation:
The question is asking us to find the difference in elevation between the Dead Sea and Athens, Greece. The Dead Sea has an elevation of 420 meters below sea level, while Athens has an average elevation of 45 meters above sea level. To find the difference, we add the absolute values of both elevations:
Absolute elevation of the Dead Sea: |-420 meters| = 420 meters below sea level
Absolute elevation of Athens: |45 meters| = 45 meters above sea level
Summing both values gives us:
420 meters + 45 meters = 465 meters
Therefore, the difference in elevation between the Dead Sea and Athens is 465 meters.
