The Baikal Rift Zone, the bottom of Lake Baikal is the deepest continental rift on the earth. The Gulf of Suez Rift; Throughout the Basin and Range Province in North America; The Rio Grande Rift in the southwestern US; The rift zone that contains the Gulf of Corinth in Greece
A rift zone is a feature of some volcanoes, especially shield volcanoes, in which a set of linear cracks (or rifts) develops in a volcanic edifice, typically forming into two or three well-defined regions along the flanks of the vent. [1]
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 East African Rift (EAR) or East African Rift System (EARS) is an active continental rift zone in East Africa. The EAR began developing around the onset of the Miocene, 22–25 million years ago. [1] It was formerly considered to be part of a larger Great Rift Valley that extended north to Asia Minor.
The Rio Grande rift is a north-trending continental rift zone. It separates the Colorado Plateau in the west from the interior of the North American craton on the east. [ 1 ] The rift extends from central Colorado in the north to the state of Chihuahua , Mexico , in the south. [ 2 ]
Many existing continental rift valleys are the result of a failed arm of a triple junction, although there are three, the East African Rift, Rio Grande rift and the Baikal Rift Zone, which are currently active, as well as a fourth which may be, the West Antarctic Rift System.
Continental-continental divergent/constructive boundary Oceanic divergent boundary: mid-ocean ridge (cross-section/cut-away view). In plate tectonics, a divergent boundary or divergent plate boundary (also known as a constructive boundary or an extensional boundary) is a linear feature that exists between two tectonic plates that are moving away from each other.
A rift is the result of pulling apart or extension of lithosphere, including the crust, caused by mantle upwelling where hotter asthenosphere magma rises up into the colder lithosphere to stretch and thin it. The internal dynamics of a rift system. The triple rift is thought to have begun in the Late Cretaceous epoch to the Paleogene period. At ...
