WebAn active continental margin is found on the leading edge of the continent where it is crashing into an oceanic plate. An excellent example is the west coast of South America. Active margins are commonly the sites of tectonic activity: earthquakes, volcanoes, mountain building, and the formation of new igneous rock. http://earthguide.ucsd.edu/eoc/eoc_teachers_hs_earth/content_tectonics/p_definition_platemargins.html

WebIntra-plate volcanism occurs when rifting of the plate occurs. But you don't necessarily need a hotspot (or rather a mantle plume) to trigger a rifting process. There are two types of rifting: Active rifting, which indeed implies the rise of a mantle plume under the lithosphere. This yields to the bulging of the lithosphere, then to its extension. WebJan 1, 2015 · Passive margins are the most common type of crustal boundary on Earth with present-day passive margins having an aggregate length of 105,000 km which is greater than either spreading ridges (65,000 km) or convergent plate boundaries (53,000 km) (Bradley, 2008; Fig. 1 ).

WebThe theory of plate tectonics provides a basic framework for evaluating the potential for future great earthquakes to occur along major plate boundaries.

WebBecause the edges of the continents on opposite sides of the divergent boundary are considered tectonically inactive, they are called passive continental margins. Divergent boundaries can also extend across continental crust – such as where the Arabian Plate is moving away from the African Plate and in the process creating the Red Sea Rift.
