It's important to understand that this is an average level. The actual elevation of the ocean can vary due to factors like:
* Tides: The gravitational pull of the moon and sun cause the ocean to rise and fall in a cyclical pattern.
* Waves: Wind and other forces create waves that temporarily raise and lower the ocean surface.
* Ocean currents: The movement of large masses of water can create variations in ocean elevation.
* Atmospheric pressure: Changes in air pressure can also influence the ocean's surface level.
While the average ocean level is considered to be 0 meters, it's important to remember that these variations exist and can significantly impact coastal areas.
