Stone mountain is 1686 feet above sea level. Lake lanier lowest depth is 160 feet below sea level. What is the difference between these two elevation

Difference between the two elevations = 1846 ft

Step-by-step explanation:

We are given that;

Stone mountain is 1686 feet above sea level

Lake lanier lowest depth is 160 feet below sea level

Now, elevations at sea level is 0 ft while those below are negative and those above are positive.

Thus;

Elevation of Lake lanier = - 160 ft

While elevation of stone mountain remains 1686ft.

Thus, difference in elevation = 1686 - (-160) = 1686 + 160 = 1846 ft
