What is the definition of sea level?

Back

Sea level is the average height of the ocean's surface, used as a base reference for measuring elevation and depth on Earth.

Front

How do you calculate the distance between two points with different elevations?

Back

To calculate the distance between two points with different elevations, subtract the lower elevation from the higher elevation.
