The active boundary between plates
WebApr 9, 2024 · An 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. WebA look at the plate tectonic map of the world shows that the west coast of North America is along a geologically active boundary between plates, whereas New England is in the middle of a large plate. The implications for earthquakes can be seen by comparing the plate tectonic map with the map of worldwide earthquakes.

At constructive plate boundaries, the tectonic plates are moving away from one another. The Earth’s crust is pulled apart to create a new pathway for rising hot magma to flow on to the surface. Volcanoes can sometimes form in these setting; one example is Iceland.
WebAug 21, 2024 · The Caribbean plate is roughly rectangular, and it slides eastward at about 2 cm/yr relative to the North American plate. Motion along its northern boundary (in the plate boundary zone region) is dominantly strike-slip (sideways motion between the plates), with a small component of subduction (one plate sinks under the other plate). WebJan 29, 2024 · The zones along plate boundaries are the most geologically active regions on Earth. Earthquakes are common along all types of boundaries and occur all over the world.
