There are some areas of land on Earth that are below sea level. Imagine you are at the Dead Sea in Africa, which has an elevation of about −1,410 feet (1,410 feet below sea level). You then climb up 125 feet. What is your new elevation?

Answer 1

If you are at the Dead Sea, which has an elevation of about -1,410 feet (1,410 feet below sea level), and you climb up 125 feet, you would add 125 feet to the elevation.

Starting elevation: -1,410 feet
Climb: +125 feet

New elevation = -1,410 + 125 = -1,285 feet

So your new elevation would be -1,285 feet (1,285 feet below sea level).
