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.
Three types of plate boundary Convergent boundary Divergent boundary Transform boundary. Tectonic plate interactions are classified into three basic types: [1] Convergent boundaries are areas where plates move toward each other and collide. These are also known as compressional or destructive boundaries.
Map showing Earth's principal tectonic plates and their boundaries in detail. These plates comprise the bulk of the continents and the Pacific Ocean.For purposes of this list, a major plate is any plate with an area greater than 20 million km 2 (7.7 million sq mi)
A mid-ocean ridge (MOR) is a seafloor mountain system formed by plate tectonics. It typically has a depth of about 2,600 meters (8,500 ft) and rises about 2,000 meters (6,600 ft) above the deepest portion of an ocean basin. This feature is where seafloor spreading takes place along a divergent plate boundary. The rate of seafloor spreading ...
Three types of plate boundaries exist, [16] characterized by the way the plates move relative to each other. They are associated with different types of surface phenomena. The different types of plate boundaries are: [17] [18] Divergent boundary. Divergent boundaries (constructive boundaries or extensional boundaries). These are where two ...
Globally most fault zones are located on divergent plate boundaries on oceanic crust. This means that they are located around mid-ocean ridges and trend perpendicular to them. The term fracture zone is used almost exclusively for features on oceanic crust; similar structures on continental crust are instead termed transform or strike slip faults.
The western edge of the African plate is a divergent boundary with the North American plate to the north and the South American plate to the south which forms the central and southern part of the Mid-Atlantic Ridge.
The Afar triple junction (also called the Afro-Arabian rift system) is located along a divergent plate boundary dividing the Nubian, Somali, and Arabian plates. This area is considered a present-day example of continental rifting leading to seafloor spreading and producing an oceanic basin.
