Go do your homework.

It looks like an ocean it's surface area is 63,800,000 square miles
No you would measure it in kilos, because its mass and volume are too great to measure in liters alone.
I think it descended -148
Technically, No. Water in a glass (or other vessel) has a curved surface known as a meniscus. A large body of water (like an ocean) actually follows the curve of the earth. So the surface of the water is a curve or section of a sphere.
The satellite measures the height above the ocean surface by sending out a pulse and timing its return to the satellite. The difference between the two is the height of the ocean surface at a given location.
Satellites use radar altimeters that are specially made tomeasurethe height of the ocean surface. The satellitesmeasurethe height of the ocean surface with an accuracy of 3cm realitve to the center of the earth.
The height of the surface of the ocean is referred to as sea level.
The term "sea level" refers to the height of an ocean's surface.
Sea Level
Bih
By bouncing microwaves off the ocean surface.
In most cases the answer is no, a tsunami will only raise the surface of the ocean a few inches, but as it gets closer to land and the sea bed shallows the water will push up and begin to form a wave. The wave would only be visible to the eye closest to the shore. Satellites have been used to measure the small difference in the ocean height to track the paths of tsunamis
Depth is a measure of distance between the surface and the ocean floor.
Sea level would be the name.
Yes it is.
