The World Ocean. For example, the Law of the Sea states that all of the World Ocean is "sea", [8] [9] [10] [b] and this is also common usage for "the sea". Any large body of water with "Sea" in the name, including lakes. River – a narrow strip of water that flows over land from a higher elevation to a lower one
A seamount is a large submarine landform that rises from the ocean floor without reaching the water surface (), and thus is not an island, islet, or cliff-rock.Seamounts are typically formed from extinct volcanoes that rise abruptly and are usually found rising from the seafloor to 1,000–4,000 m (3,300–13,100 ft) in height.
A sea is a large body of salt water. There are particular seas and the sea. The sea commonly refers to the ocean, the interconnected body of seawaters that spans most of Earth. Particular seas are either marginal seas, second-order sections of the oceanic sea (e.g. the Mediterranean Sea), or certain large, nearly landlocked bodies of water.
The zone where land meets sea is known as the coast, and the part between the lowest spring tides and the upper limit reached by splashing waves is the shore. A beach is the accumulation of sand or shingle on the shore. [62] A headland is a point of land jutting out into the sea and a larger promontory is known as a cape. The indentation of a ...
The flat top is a summit plateau with a width of 8.0 kilometres (5 mi) [2] and as more recently determined 11 by 8.5 kilometres (6.8 mi × 5.3 mi) [14] at a mean depth of 73 metres (40 fathoms) [3] and has been named Emerson Plateau; it has a vaguely triangular shape pointing west, and Collins Point lies close to the western margin of the ...
The Gulf of California (Spanish: Golfo de California), also known as the Sea of Cortés (Mar de Cortés) or Sea of Cortez, or less commonly as the Vermilion Sea (Mar Vermejo), is a marginal sea of the Pacific Ocean that separates the Baja California peninsula from the Mexican mainland.
Height above mean sea level (AMSL) is the elevation (on the ground) or altitude (in the air) of an object, relative to a reference datum for mean sea level (MSL). It is also used in aviation, where some heights are recorded and reported with respect to mean sea level (contrast with flight level ), and in the atmospheric sciences , and in land ...
Researchers speculate that Davidson Seamount is an ideal habitat for deep-sea corals and sponges because it has favorable bottom rock (bare lava rock), a steady food supply (supplied by a water current favoring the seamount; see the section above), and has not been disturbed by strong bottom currents than often bother other seafloor areas.
