Called 'TIDES' That is when the moon's gravity causes the seawater to raise in some areas when it on one face of the earth, and lets low tides come in when it is not facing the particular area of the ocean anymore. Also, the ice caps at the Northpole and Southpole are melting slowly as the years pass, such as to cause a gradual rise in the overall ocean depths. It's called 'GLOBAL WARMING'
The rise and fall is the tides.
That would be TIDE.

rise and fall of the sea!!!!!!
The gravitational attraction from the Moon and Sun, causes the tides.
It does not rise or fall. It is an imaginary line.
Fall is the height of a slanted or diagonal straight surface. Gradient is the result of rise divided by fall (rise/fall) (rise over fall)
Sea levels rise with the tides.
