Of course, divergent plate boundaries also exist on land. The East African Rift is an example of a single tectonic plate being ripped in two. WebSep 8, 2024 · Continental rifts. On a continent, a divergent boundary appears as a rift. A rift forms when a single plate begins to break apart, or when previously fused plates begin to separate again. When a rift occurs in continental crust, elongated fissures (faults) begin to form in the crust as it thins and stretches.

WebJan 17, 2024 · Divergent boundaries exist where tectonic plates move apart from each other. Unlike convergent boundaries, divergence occurs between only oceanic or only continental plates, not one of each. The vast majority … At divergent boundaries, two plates move away from each other and the space that this creates is filled with new crustal material sourced from molten magma that forms below. The origin of new divergent boundaries at triple junctions is sometimes thought to be associated with the phenomenon known as hotspots. Here, exceedingly large convective cells bring very large quantities of hot asthenospheric material near the surface, and the kinetic energy is thought to b…
