It is the continental shelf.
The portion of a continent that is submerged beneath the ocean is called the Continental Shelf.
The land under an ocean at the edge of a continent is called the continental shelf. This is the shallow submerged portion of a continent that extends from the shoreline to the continental slope.
The part of the continent that is under water is known as the continental shelf. This is the submerged portion of a continent that extends from the shoreline to a steeper drop-off point called the continental slope.
The portion of a continent that is submerged beneath the ocean is called the Continental Shelf.
continental shelf peninsula
The portion of the land mass that extends into the ocean is called the coastline or shoreline.

The slope is the steep incline at the edge of the continental shelf that descends into the ocean depths. The continental shelf is a gently sloping, submerged portion of a continent that extends from the shoreline to the shelf break where the slope begins.
The portion of an iceberg that is submerged generally melts more slowly than the part above water. This is because the submerged section is insulated by the surrounding water, which remains relatively cold, while the exposed portion is directly exposed to warmer air temperatures. Additionally, the melting process is influenced by factors like air temperature, wind, and sunlight, which primarily affect the visible part of the iceberg. Thus, the above-water portion tends to melt faster than the submerged part.
The "continental shelf" is generally considered to be up to the 600-foot depth. Along the Atlantic coast, that extends a hundred miles or more. On the Pacific side, there really is no continental shelf; we have deep water only a couple of miles off the coast.
The portion of the continental margin that serves as a boundary between the oceanic crust and the continental crust is known as the continental slope. This region transitions from the relatively shallow continental shelf to the steeper continental rise, leading down to the deep ocean floor. The slope marks the edge of the continental crust, where it meets the denser oceanic crust beneath the ocean.
The continental shelf starts from the shore to a few miles out with less gradient of slope. The continental slope starts after shelf-break with a higher slope gradient, then follows the continental rise and abyssal-plain.
