Question

A. A fish is 12 m below the surface of the ocean. What is its elevation?

B. A seabird is 28 m above the surface of the ocean. What is its elevation?
C. If the bird is directly above the fish, how far apart are they?

Answer 1

1.) -12

2.) 28

3.) 40

Explanation:

The elevation of an object is the height or depth of the object relative to the sea level. If the object is above sea level, its elevation will be positive. However, if the object is below sea level, its elevation will be negative. Therefore, we can conclude that the elevation of the fish is -12 m because it is below sea level.
