WebJan 20, 2024 · The oceanic plates are themselves formed from the divergent boundary, so probably not. Even if a new rifting occurred exactly at the boundary, the result would eventually be that the ocean floor surrounds the divergent boundary. A very simplified model of an ocean would have a divergent boundary in the middle. WebJan 11, 2024 · A divergent plate boundary can also occur on a continent. This is called continental rifting.

WebThe exact mechanism of rift formation is an on-going debate among geologists and geophysicists. One popular model for the EARS assumes that elevated heat flow from the mantle (strictly the asthenosphere) is causing a pair of thermal "bulges" in central Kenya and the Afar region of north-central Ethiopia.

WebJan 11, 2024 · A divergent plate boundary on land rips continents apart ( Figure below). When plate divergence occurs on land, the continental crust rifts, or splits. This effectively creates a new ocean basin as the pieces of the continent move apart. WebDivergent boundaries can be mid-ocean ridges or continental rift valleys. At these boundaries, two neighboring plates move away from each other. Continental rift valleys are characterized by normal faulting and basalt-rich volcanoes. The diagram shows a typical continental rift. Note the central rift valley that includes volcanoes.
