The residents of a village want to paint a sign that shows the elevation of their village relative to the sea. Their altimeter shows +2,100 feet. What should their signboard read?
A. 2,100 feet above sea level
B. 2,100 feet below sea level
C. -2,100 feet above sea level
D. +2,100 feet below sea level
Step-by-step explanation
Depth above water levels refers to a location's peak just above ocean.
If indeed the height is positive (+) then the depth might well just above water level and if negative (-) therefore the depth will be lower than the water level.
