The Mid-Atlantic Ridge is a mid-ocean ridge (a divergent or constructive plate boundary) located along the floor of the Atlantic Ocean, and part of the longest mountain range in the world. In the North Atlantic, the ridge separates the North American from the Eurasian plate and the African plate , north and south of the Azores triple junction .
Major fractures zones of the Atlantic can be seen on this ocean depth map Active Atlantic Ocean fracture zones are perpendicular to the mid-ocean ridges (black lines) in orange shaded region In the Atlantic Ocean most fracture zones originate from the Mid-Atlantic Ridge , which runs from north to south, and are therefore west to east oriented ...
The Mid-Atlantic Ridge system separates the North American plate and the South American plate in the west from the African plate and the Eurasian plate in the east; The Gakkel Ridge is a slow spreading ridge located in the Arctic Ocean; The East Pacific Rise, extending from the South Pacific to the Gulf of California; The Baikal Rift Zone in ...
Silfra fissure The Mid-Atlantic Ridge passing through Þingvellir Rocks and boulders that have piled up in the fissure due to earthquakes.. Silfra (Icelandic pronunciation: [ˈsɪl(v)ra]) is a rift formed in the Mid-Atlantic Ridge – the divergent tectonic boundary between the North American and Eurasian plates – and is located in the Þingvallavatn Lake in the Þingvellir National Park in ...
The Midcontinent Rift System (MRS) or Keweenawan Rift is a 2,000 km (1,200 mi) long geological rift in the center of the North American continent and south-central part of the North American plate. It formed when the continent's core, the North American craton , began to split apart during the Mesoproterozoic era of the Precambrian , about 1.1 ...
The Mid-Atlantic Ridge stretches 10,000 miles from north to south, and is considered “the longest mountain range in the world and one of the most prominent geological features on Earth,” NOAA ...
The creation of this earthquake epicenter map proved to be a useful secondary dataset for examining the bathymetry of the Mid-Atlantic Ridge. When Foster's map of earthquake epicenters was overlaid with Tharp's profile of the Mid-Atlantic Ridge, it became clear that the location of these earthquakes aligned with Tharp's rift valley.
This can apply even in the hours between 8 a.m. and 1 p.m. when the map of the Atlantic showed two “X” marks representing systems and five hours later the map’s spotless.
