Crust is created what boundary

WebThere are four types of plate boundaries: Divergent boundaries -- where new crust is generated as the plates pull away from each other. Convergent boundaries -- where crust is destroyed as one plate dives under … WebJul 16, 2024 · The geometry of the upper ("rhyolite partial melt") and lower ("basaltic partial melt") crustal magma reservoirs is based on the reduction in seismic-wave velocity compared to normal crustal seismic velocities. The dashed outline of the lower magma reservoir indicates that its boundaries are uncertain.

WebAt divergent boundaries, lithospheric plates move apart and crust is created. Earth's crust is fractured into approximately 20 lithospheric plates. Each lithospheric plate is composed of a layer of oceanic crust or continental crust superficial to an outer layer of the mantle. WebJan 11, 2024 · A divergent plate boundary can also occur on a continent. This is called continental rifting. Magma rises beneath the continent. The crust thins, breaks, and then splits apart. This first produces a rift valley. The East African Rift is a rift valley. Eastern Africa is splitting away from the African continent. dugine boje pred ocima https://pammiescakes.com
