Question

Elevation is a measure of height in relation to sea level. The highest feature on Earth is Mount Everest with an elevation +29,029 feet. The lowest feature on Earth is the Challenger Deep with an elevation -35,797 feet. What elevation does sea level represent in this scenario? Which feature is farther from sea level?

Answer 1

`Sea\ Level = 0\ ft`

The farthest point is the Challenger Deep

Explanation:

Given

`Highest = +29029ft`

`Least = -35,797ft`

Solving (a): The sea level

Both elevations had signs in front of them.

The sea level is the point at the neutral level, neither positive nor negative.

Hence:

`Sea\ Level = 0\ ft`

Solving (b): Farthest Point.

The farthest point is the one with the highest magnitude.

Comparing

`Highest = +29029ft` to
`Least = -35,797ft`

-35,797 ft has the highest magnitude.

Hence:

The farthest point is the Challenger Deep
