Basically cataclysm. Because of the rapid changes in the earths level, im guessing you mean. Would mean that there would be too much ocean floor, and the cause would be if you meant the Earth would happen, well not much just we would lose a lot of water from the ocean.
Many volcanos occur along tectonic boundaries, whether they are convergent (pushing together) or divergent (pulling apart). These boundaries typically occur between continental and oceanic plates or between two oceanic plates. Some volcanos however are created by hot spots where molten magma from the mantle of the Earth pushes through the crust, these hot spots can form islands such as the Hawaiian Islands.
An equal amount of oceanic crust is being subducted at the convergent plate boundaries as is being created at the mid-oceanic ridge.
it's neither created or destroyed
well, there are three different types of things that could happen ,if two plates are pushing towards each other these plates are called destructive plate boundaries, here the land is destroyed, they could be moving away from each other these would be called constructive her land is created, they could be sliding past each other these are named conserve
The Mid-Atlantic Ridge is a divergent plate boundary, also known as a spreading center.
At divergent plate boundaries, crust is formed through the process of seafloor spreading. At convergent plate boundaries, crust is often destroyed through subduction, where one plate is forced beneath another into the mantle. At transform plate boundaries, crust is neither created nor destroyed, as the plates slide past each other horizontally.
Volcanoes are more common along convergent boundaries where two tectonic plates collide, causing subduction and the melting of rock. Divergent boundaries also have volcanoes, but they are typically less explosive and occur as a result of magma rising to fill the gap created by the moving plates.
No, new crust is not created at a convergent boundary. Instead, at convergent boundaries, two tectonic plates come together and one plate is usually forced beneath the other in a process called subduction. This process can lead to the destruction of crust rather than the creation of new crust.
Subduction zones are boundaries where the seafloor is destroyed. This happens when one tectonic plate moves beneath another, causing it to sink into the mantle and be reabsorbed. This process can lead to the formation of deep ocean trenches and volcanic arcs on the Earth's surface.
Both involve tectonic plate moving relative to one another and help recycle oceanic crust. At divergent boundaries plates move away from each other and new crust is created. At most convergent boundaries oceanic crust is destroyed.Both of these boundary types produce volcanoes.
Seafloor is created at divergent plate boundaries called the mid-ocean ridges.
Boundaries, or faults, are locations on the edges of plates, crustal masses that are very slowly moving atop the convective outer mantle (asthenosphere).At convergent boundaries, two crustal masses (plates) are pushing into each other. This can result in subduction, so may be a destructive boundary.At divergent boundaries, two masses of rock are pulling away from each other. This can be a constructive boundary when it produces rifting and seafloor spreading.At transform boundaries, or transform faults, rock masses move past one another. These are known as conservativeboundaries because crust is neither destroyed or created.(these can cause earthquakes when accumulated strain is released)
along divergent boundaries tectonic plates move apart & rifts are created
The sea floor is destroyed in subduction zones, where one tectonic plate is pushed beneath another. This process is responsible for the destruction of oceanic crust and the formation of deep ocean trenches.
Convergent (or destructive): Where two plates are moving toward each other. Collisions between oceanic plates results in subduction of the more dense plate. Collisions between an oceanic plate and a continental plate may result in the subduction of the oceanic plate because oceanic plates are more dense than continental plates. Collisions between two continental plates results in uplift and mountain formation where neither plate subducts.Divergent (or constructive): Where two plates are moving away from each other. Divergent plate boundaries are the site of new crust formation, particularly at the mid-ocean ridges, where spreading plates are infilled with basaltic magma from the asthenosphere.Transform (or conservative): Where two plates slide (actually 'grind') alongside each other and neither plate subducts. Earthquakes are common at transform faults due to the grinding and snapping movements of the plates as they move.
Mountain ranges can be created at all three types of plate boundaries in California: convergent boundaries (e.g. Sierra Nevada Mountains), divergent boundaries (e.g. Basin and Range Province), and transform boundaries (e.g. San Gabriel Mountains).
Mountains - formed by convergent plate boundaries where plates collide and are pushed upward. Rift valleys - formed by divergent plate boundaries where plates move apart, creating a depression in the earth's crust. Faults - fractures in the earth's crust caused by plates rubbing against each other. Folded mountains - created by the folding of rock layers due to compression at convergent plate boundaries. Volcanoes - formed at convergent and divergent plate boundaries where magma rises to the surface through the crust.
