The Sea SVG is a part of the World Ocean, isolated by land or underwater elevations. It also differs from the World Ocean by its hydrological, meteorological and climatic regimes, which is due to their marginal position relative to the oceans and the slowdown in water exchange due to the limited connection with the open part. The seas are also separated according to their flora and fauna (e.g., the Aegean Sea is in the Mediterranean). Endemics are common in marine fauna.
For various authors, particularly in the Bible, seas can be called any large water area (rivers, lakes, bays); for example, the Egyptian Sea (Isaiah 11:15) in the Bible, according to various assumptions, denotes either the Nile River or part of the Red Sea, in addition, it is called the Euphrates River by the Sea SVG.
The Dal’s explanatory dictionary defines the sea as an accumulation of bitter-saline waters in vast depressions or fractures of the earth’s surface. Thus, the sea is all these arbitrarily delimited waters as opposed to the land (land, continent). Usually seas communicate with the world ocean by means of straits (for example, Mediterranean, Black and others) and bear this name correctly. Less legally it is given to shallow seas or fresh lakes (for example, Caspian Sea, Aral, Baikal – “Glorious sea – sacred Baikal”). Besides, the sea means abyss or abyss, immensity.
Objects called seas exist not only on the Earth: for example, “South Sea” is on Mars and on the Moon (lunar sea is called (visually) a dark spot on the surface of the lunar disk).
When cooled down, the salt water turns into “sea ice” – this happens below the freezing point for fresh water at a temperature of about -1.8 °C.
Sea SVG General information
According to the degree of isolation and peculiarities of the sea hydrological regime, they are divided into 3 groups: inland seas (Mediterranean and semi-enclosed seas), marginal seas and inter-island seas. Geographically, Mediterranean seas are sometimes divided into intercontinental and inland seas.
From a geological point of view, modern seas are young formations. In the outlines close to the present, they were all defined in the Palaeogene-Neogene period and finally formed in the anthropogenesis. The deepest seas (e.g., the Mediterranean Sea) are formed in the places of large fractures of the Earth’s crust, and shallow seas appeared during the flooding of the marginal parts of the continents by the waters of the World Ocean and are usually located on the continental shelf.
In 1978, the International Maritime Organization established World Maritime Day. This day is a part of the UN system of world and international days. In addition, the Day of the Sea is celebrated as a national holiday in Japan, and the Baltic Sea Day is celebrated in Russia. The paintings depicting the sea are highlighted in a separate genre – marina.
