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
