Full solution

Q. Geographers use negative numbers to represent points below sea level and positive numbers to represent points above sea level. For example, the lowest point in New Orleans is at

-2

meters, and the highest point is at

6

meters.

\newline

What does

0

meters represent?

\newline

Choose

1

answer:

\newline

(A) Sea level

\newline

(B) The highest point in New Orleans

\newline

(C) The lowest point in New Orleans

Sea Level Reference: Geographers' convention is that $0$ meters represents sea level. This is a standard reference point used worldwide to differentiate between points that are below sea level (negative numbers) and points that are above sea level (positive numbers).
New Orleans Elevations: Since the lowest point in New Orleans is at $-2$ meters (below sea level) and the highest point is at $6$ meters (above sea level), $0$ meters would logically be the point that is neither above nor below sea level, which is sea level itself.
Mathematical Confirmation: To confirm, we can check if there is any mathematical operation needed to find the answer. Since $0$ is the neutral element in addition and subtraction, it does not change the value of other numbers, indicating that it is the baseline or reference point, which in this context is sea level.
