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 ...
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 ...
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.
Rheic Ocean, the Paleozoic ocean between Gondwana and Laurussia; Slide Mountain Ocean, the Mesozoic ocean between the ancient Intermontane Islands (that is, Wrangellia) and North America; South Anuyi Ocean, Mesozoic ocean related to the formation of the Arctic Ocean; Tethys Ocean, the ocean between the ancient continents of Gondwana and Laurasia
The blue whale (Balaenoptera musculus) is the largest cetacean on the planet. While some have claimed that there were dinosaurs that topped its size, there is no scientific data to support that ...
A massive jawbone found by a father-daughter fossil-collecting duo on a beach in Somerset along the English coast belonged to a newfound species that’s likely the largest known marine reptile to ...
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 ...
Recent studies indicate a large underground saltwater ocean present on Ganymede, Jupiter’s largest moon, with estimated water volume eight times greater than Earth’s world ocean. [3] The fourth largest of Jupiter’s moons, Europa, while smaller than Earth’s moon, ranks fourth in water volume, estimated to be twice more than on Earth. [2]
