Ocean – the four to seven largest named bodies of water in the World Ocean, all of which have "Ocean" in the name (see: Borders of the oceans for details). Sea has several definitions: [a] A division of an ocean, delineated by landforms, [6] currents (e.g., Sargasso Sea), or specific latitude or longitude boundaries. This includes but is not ...
At 165,250,000 square kilometers (63,800,000 square miles) in area (as defined with a southern Antarctic border), the Pacific Ocean is the largest division of the World Ocean and the hydrosphere and covers about 46% of Earth's water surface and about 32% of the planet's total surface area, larger than its entire land area (148,000,000 km 2 ...
Principal language families of the world (and in some cases geographic groups of families). For greater detail, see Distribution of languages in the world. This is a list of languages by total number of speakers. It is difficult to define what constitutes a language as opposed to a dialect.
The borders of the oceans are the limits of Earth's oceanic waters.The definition and number of oceans can vary depending on the adopted criteria. The principal divisions (in descending order of area) of the five oceans are the Pacific Ocean, Atlantic Ocean, Indian Ocean, Southern (Antarctic) Ocean, and Arctic Ocean.
Watch to learn all about this king of the ocean! The blue whale (Balaenoptera musculus) is the largest cetacean on the planet. While some have claimed that there were dinosaurs that topped its ...
The entire ocean, containing 97% of Earth's water, spans 70.8% of Earth's surface, [8] making it Earth's global ocean or world ocean. [23] [25] This makes Earth, along with its vibrant hydrosphere a "water world" [43] [44] or "ocean world", [45] [46] particularly in Earth's early history when the ocean is thought to have possibly covered Earth ...
Gulf of Panama in the Pacific Ocean south of Panama; Gulf of Paria, in the Caribbean Sea between Trinidad and Tobago and Venezuela; Gulf of Saint Lawrence, the world's largest estuary and the outlet of the Saint Lawrence River into the Atlantic Ocean; San Jorge Gulf, in Patagonian Southern Atlantic Ocean; San Matias Gulf, in Patagonian Southern ...
The mass of this world ocean is 1.35 × 10 18 metric tons or about 1/4400 of Earth's total mass. The world ocean covers an area of 3.618 × 10 8 km 2 with a mean depth of 3682 m, resulting in an estimated volume of 1.332 × 10 9 km 3. [17] If all of Earth's crustal surface was at the same elevation as a smooth sphere, the depth of the resulting ...
