Just as new oceanic crust forms at mid-ocean ridges, old oceanic crust is destroyed at subduction zones.

Does Rhyolitic magma forms beneath continental or oceanic crust?
continental crust
Does granitic crust form at the mid oceanic ridge?
Granitic crust does not form at the mid-oceanic ridge. Rather another type of igneous rock Basalt is formed at the Mid-Oceanic ridge. Both are silicate rocks and have a high oxygen and silica content. The difference is that Granite is formed intrusively, that is within the Earth's crust. Basalt is extrusive, that is it is formed above the Earth's surface, such as at the bottom of the ocean at the Mid-Oceanic ridge.
What are places where oceanic crust sinks back to the mantle?
No. Mid oceanic ridges are the places where new oceanic crust are forming.
Are land forms and water bodies different?
Yes and No. Fundamentally Earth's tectonic processes have made two forms of Crust. New(ish) Oceanic crust (which underlies the Oceans) and Old Continental Crust (which forms the Land/Continents). Thus the Oceans and the Contents are different. However while the basic shape of the Oceanic crust is similar in all oceans (mid oceanic ridges, abyssal planes, continental slopes and deep see trenches), The Continental crust is much more varied and in basins shaped land forms in this crust water accumulates. In this instance these water bodies are therefore just another land form feature, a result of underlying topography.
Which forms at mid-ocean ridges?
New oceanic crust is created along mid ocean ridges. These are areas of the earth where there is divergence or splitting of the ocean floor and basaltic magma oozes out from within the mantle to occupy the gaps and form new crusts.
How does a trench forms?
They form when the oceanic crust goes under the Continental crust. The oceanic crust then forms the trenches through a process called subduction.
What type of rock makes up the continental and oceanic crust?
basalt forms in oceanic crust granite forms in continental
What happens when a plate of oceanic crust collides with a plate of Continetal crust why?
the oceanic crust slides down and burns in the mantle and forms a volcano
Does Rhyolitic magma forms beneath continental or oceanic crust?
continental crust
How does trench formed?
They form when the oceanic crust goes under the Continental crust. The oceanic crust then forms the trenches through a process called subduction.

How does a deep-ocean trench form?
They form when the oceanic crust goes under the Continental crust. The oceanic crust then forms the trenches through a process called subduction.
How is oceanic crust forms?
Rewrite the question as is is not proper English
How iron forms?
It is formed when the Earth was being formed. As the Earth got bigger the iron seeped into the crust of the earth and kept going.
What feature forms at diverging oceanic plates?
Ridges of buoyant oceanic crust form at diverging oceanic plate boundaries.
What are places where oceanic crust sinks back to the mantle?
No. Mid oceanic ridges are the places where new oceanic crust are forming.
How and why does an oceanic trench form?
The earth has plates and when the earth shirfts its plates it open a trench canyon like structure. sorry if my grammer is not perfect. An oceanic trench forms when a denser plate is subducted into the Earth at a convergent plate margin. Because the denser plate (always oceanic crust) is being bent and pulled down into the mantle, a trench forms at this subduction zone.
