Sea

A sea is a large body of salt water that is surrounded in whole or in part by land. More broadly, "the sea" is the interconnected system of Earth's salty, oceanic waters—considered as one global ocean or as several principal oceanic divisions. The sea moderates Earth's climate and has important roles in the water cycle, carbon cycle, and nitrogen cycle. Although the sea has been travelled and explored since prehistory, the modern scientific study of the sea—oceanography—dates broadly to the British Challenger expedition of the 1870s. The sea is conventionally divided into up to five large oceanic sections—including the IHO's four named oceans (the Atlantic, Pacific, Indian, and Arctic) and the Southern Ocean; smaller, second-order sections, such as the Mediterranean, are known as seas.

Owing to the present state of continental drift, the Northern Hemisphere is now fairly equally divided between land and sea (a ratio of about 2:3) but the South is overwhelmingly oceanic (1:4.7).Salinity in the open ocean is generally in a narrow band around 3.5% by mass, although this can vary in more landlocked waters, near the mouths of large rivers, or at great depths. About 85% of the solids in the open sea are sodium chloride. Deep-sea currents are produced by differences in salinity and temperature. Surface currents are formed by the friction of waves produced by the wind and by tides, the changes in local sea level produced by the gravity of the Moon and Sun. The direction of all of these is governed by surface and submarine land masses and by the rotation of the Earth (the Coriolis effect).

Utopia

A utopia (/juːˈtoʊpiə/ yoo-TOH-pee-ə) is a community or society possessing highly desirable or near perfect qualities. The word was coined by Sir Thomas More in Greek for his 1516 book Utopia (in Latin), describing a fictional island society in the Atlantic Ocean. The term has been used to describe both intentional communities that attempt to create ideal societies, and the imagined societies portrayed in fiction. Alternative views on structural and qualitative attributes of society have spawned other concepts, most prominently dystopia.

Etymology

The term utopia was coined in Greek by Sir Thomas More for his 1516 book Utopia, describing a fictional island society in the Atlantic Ocean.

The word comes from the Greek: οὐ ("not") and τόπος ("place") and means "no-place", and strictly describes any non-existent society 'described in considerable detail'. However, in standard usage, the word's meaning has narrowed and now usually describes a non-existent society that is intended to be viewed as considerably better than contemporary society.Eutopia, derived from the Greek εὖ ("good" or "well") and τόπος ("place"), means "good place", and is strictly speaking the correct term to describe a positive utopia. In English, eutopia and utopia are homophonous, which may have given rise to the change in meaning.
