Seafloor spreading, or seafloor spread, ... These areas are named triple junctions and can be found in several places across the world today.
Harry Hess proposed the seafloor spreading hypothesis in 1960 (published in 1962 [1]); the term "spreading of the seafloor" was introduced by geophysicist Robert S. Dietz in 1961. [2] According to Hess, seafloor was created at mid-oceanic ridges by the convection of the Earth's mantle, pushing and spreading the older crust away from the ridge. [3]
In the 1960s, geologists discovered and began to propose mechanisms for seafloor spreading. The discovery of mid-ocean ridges and the process of seafloor spreading allowed for Wegener's theory to be expanded so that it included the movement of oceanic crust as well as the continents. [49]
An underwater mountain taller than the world’s highest building has been discovered by ... is the world’s tallest building at a height of 2,722ft (830m). ... The seafloor feature was ...
The seabed (also known as the seafloor, sea floor, ocean floor, and ocean bottom) is the bottom of the ocean. All floors of the ocean are known as 'seabeds'. The structure of the seabed of the global ocean is governed by plate tectonics. Most of the ocean is very deep, where the seabed is known as the abyssal plain. Seafloor spreading creates ...
The world's largest coral has been discovered by a National Geographic expedition to the Solomon Islands. ... spreading forever along the seafloor,” Timmers said in a statement. ...
With active tectonic spreading, the MAR is the site of frequent earthquakes,” NOAA reports. “Hydrothermal vents may form where magma provides heat as it rises to the seafloor.
World War II in the Pacific led to great improvements of bathymetry, particularly in the western Pacific. In light of these new measurements, the linear nature of the deeps became clear. There was a rapid growth of deep sea research efforts, especially the widespread use of echosounders in the 1950s and 1960s.
