Yes, in many places it is. But like the surface of the earth that you can see, the ocean floor has many different topographies. The ocean floor has mountains, volcanoes, deep valleys, and reefs. There vast areas of vegetation and areas that are devoid of vegetation, often due to how deep they are and how much sunlight penetrates. There are also arctic regions of ocean floor as well as tropical regions. The ocean floor is really as varied as the continents above the water.

Since everything is measured at sea level then a continent would be above sea level thus higher than the sea floor which would be below sea level, but there are mountains under the sea that are every bit as high as the highest mountains on any continent.
It is Mount Everest
That would definitely be the sea floor
Yes, according to my professor: "The sea-floor subsides as it cools, the amount depending on the time the lithosphere has had to cool and thicken. This means that the volume of the ocean basins increases with the mean age of the ocean floor, and that sea level tends to decrease in consequence with the mean age of the ocean floor (because the same amount of sea water sits lower relative to continents). When sea floor production speeds up, as when the midocean ridge system lengthens during a supercontinent's breakup, sea level tends to rise. When sea floor production slows down, as when the midocean ridge system shortens during a supercontinent's assembly, sea level tends to fall. Thus sea level tends to rise during a supercontinent's breakup.
It continues to grow upward
The floor that looks like it has paint splatters on it is called the Oops Floor. You can get the Oops Floor at Yukea Shop on Main Street. You have to be level 9 or higher to get the Oops Floor.
You have to beat the Bowser in the Fire Sea level
The valley is about 100 feet above sea level on average. There are areas that are higher and lower, but NO PLACE in the valley is below sea level. In the past the valley floor was lower, infact it was an inland sea, but tectonic action raised the valley floor and drained out the water.
