Continental crust rifts due to tectonic forces, primarily caused by extensional stresses that pull the crust apart. This can occur at divergent plate boundaries or within continental regions where heat from the mantle creates upwelling, leading to the thinning and stretching of the crust. As the crust becomes increasingly strained, it fractures, allowing for the formation of rift valleys and eventually possibly leading to the creation of new ocean basins. The process is also influenced by geological factors such as pre-existing weaknesses and variations in temperature and composition within the crust.
What else can I help you with?
Where would you find continental crust over a divergent boundary?
Continental crust over a divergent boundary can typically be found at mid-ocean ridges, where tectonic plates are pulling apart. In some cases, such as the East African Rift, divergent boundaries can also occur on land, leading to the formation of rift valleys. These regions are characterized by volcanic activity and geological features associated with the thinning and stretching of the continental crust.
Plate tectonics what forms along continental divergent boundaries?
Along continental divergent boundaries, rift valleys or rift zones can form as the continental plates move apart. These rift zones may be accompanied by volcanic activity and seismic events as the crust stretches and thins. Over time, if the divergence continues, a new ocean basin may form as the continents separate further.
Where is there a continental-continental divergent boundary in Africa?
A continental-continental divergent boundary can be found in East Africa, specifically in the East African Rift system. This is where the African Plate is splitting apart along a fault zone, creating a rift valley with new crust forming in the middle.
What Happens to a rift valley on Continental crust?

Which can NOT form as the result of oceanic-oceanic convergence?
Continental crust cannot form as a result of oceanic-oceanic convergence. This process typically results in the formation of volcanic island arcs or deep-sea trenches. Continental crust is formed through processes like continental collision and accretion of terranes.
When continental crust begins to separate what forms?
A rift forms.
Which of the following landforms result from divergence of continental crust?
a rift valley
When two pieces of continental crust pull apart what forms?
a rift hope i helped
Deep crack in the mid-atlantic ridge?
A Rift Valley is a deep crack in the mid-Atlantic ridge. They can occur in oceanic crust or in continental crust.
How is a volcano formed at a continental rift?
A volcano is formed at a continental rift when the Earth's tectonic plates move apart, creating a gap in the Earth's crust. Magma from the mantle rises to the surface through this gap, leading to the formation of a volcano.
Where do rift zone form?
Rift zones form at locations where the Earth's tectonic plates are moving away from each other. This movement creates fractures in the Earth's crust, allowing magma to rise to the surface and form new crust. Rift zones are commonly found along mid-ocean ridges and continental rift valleys.

A rift valley can form where two continental plates are?
pulling apart. As the plates move away from each other, the crust stretches and thins, creating a low-lying area known as a rift valley. Over time, this process can lead to the formation of new ocean basins.
Where is there a continental-continental divergent boundary in Africa?
A continental-continental divergent boundary can be found in East Africa, specifically in the East African Rift system. This is where the African Plate is splitting apart along a fault zone, creating a rift valley with new crust forming in the middle.

Which boundry does a rift valley forrm at?
divergant boundries. new rock is formed and pushes the older seafloor outward towards the continental crust.
