Unix was developed using a high-level programming language (C) instead of platform-specific assembly language, enabling its portability across multiple computer platforms.
The continental shelf is an underwater landmass which extends from a continent, resulting in an area of relatively shallow water known as a shelf sea.Much of the shelves were exposed during glacial periods and interglacial periods.The shelf surrounding an island is known as an insular shelf.The continental margin, between the continental shelf and the abyssal plain, comprises a steep continental slope followed by the flatter continental rise.Sediment from the continent above cascades down the slope and accumulates as a pile of sediment at the base of the slope, called the continental rise.he shelf surrounding an island is known as an insular shelf. The continental margin, between the continental shelf and the abyssal plain, comprises a steep continental slope followed by the flatter continental rise.
The continental shelf is an undersea extension of a continent that can stretch a great distance out to sea in some cases.n some instances, the continental shelf is very short, as is the case in subduction zones where one tectonic plate is being sucked below another. A well known example can be found in the waters off the coast of Chile. In other cases, extension stretches for many miles (or kilometers) out to sea.
