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 ...
Pacific Ocean: Between 17 million and 6 million years ago, huge outpourings of flood basalt lava covered the Columbia River Plateau and forced the lower Columbia into its present course. [16] Amazon: 11.8~11.3 Atlantic Ocean: Waters worked through the sandstone from the west and the Amazon began to flow eastward. [17]
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]
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
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 ...
In ancient history, various vessels were used for coastal fishing and travel. [1] [obsolete source]. Some evidence suggesets that man may have crossed the sea as early as 700,000 years ago. The first true ocean-going boats were invented by the Austronesian peoples, using technologies like multihulls, outriggers, crab claw sails, and tanja sails.
