A constructive (divergent) plate boundary occurs where two tectonic plates are separating. Examples below include the South American Plate, the African Plate, the Eurasian Plate, and the North American Plate. Volcanoes and minor earthquakes can occur along constructive plate margins.
There are two types of locations where constructive boundaries happen:
Mid-Ocean Ridges: These are the most common form of constructive boundaries, typically located underwater, where two sections of oceanic crust move apart. An example is the Mid-Atlantic Ridge.
Continental Rift Zones: Continental rift zones form when the lithosphere stretches and fractures, leading to land sinking between faults. This process results in the formation of deep and expansive rift valleys. An example is the East African Rift Valley. Geologists widely believe this area represents the early stages of new sea formation, with the possibility of the eastern segment of Africa eventually breaking away to form a new island.
