Want this question answered?
No. Mid oceanic ridges are the places where new oceanic crust are forming.
At the opposite end of the convection current in the Earth's mantle that creates oceanic crust at the mid-ocean ridge, are trenches, where oceanic crust is diving down into the mantle. The Atlantic Ocean is expanding. The Pacific Ocean is shrinking.
Subduction of oceanic crust. The Earthquakes occur at depth in the descending slab.
Ocean trenches were discovered as a sign of destructive plate margins. These plate margins cause oceanic crust to subduct below the continental crust at the oceanic-continental boundary, and force the oceanic crust to move down into the Earth's mantle and melt into basaltic magma. As this is happening, magma at oceanic ridges is creating new oceanic crust at the mid-oceanic ridges. Overall, these two processes cancel each other out and so the total amount of oceanic crust is staying aproximately the same. Therefore the Earth is not growing. Hope this helps :)
That is normally where they would be found; farthest away from the point at which they were initially formed.
No, the theory is that Seafloor spreading state that the new ocean crust is formed at ocean ridges and is destroyed at deep sea trenches.
Crust under the oceans is called oceanic crust.
Mid-ocean ridges are the birthplace of oceanic crust. Trenches represent the destruction and burial of oceanic crust. They are at opposite ends of the Earth's convection currents that move through the asthenosphere.
Sea Floor spreading has to do with the crust forming at ocean ridges and being destroyed at deep sea trenches.
Yes
Magmatic upsurge from within the earths crust, and plumes.
No. Mid oceanic ridges are the places where new oceanic crust are forming.
Well i think that can be one of those a) oldest near ocean ridges b) Youngest hear ocean ridges c) Youngest at deep-sea trenches d) Thinnest in subduction zones
What are three geographic features that may be found at plate boundaries?
