What feature on the ocean floor would you most likely find the oldest seafloor?

in a subduction trench, because of Harry Hess' theory of sea floor spreading. Meaning that the rock is formed new at the mid-ocean ridge, and moved out towards the coasts into a subduction zone years and years later.

How would the age of the oldest rocks on the continents compare with the age of the oldest rocks on the seafloor if the rock on the continents is continually formed but not removed?
The oldest rocks on the continents would be much older than the rocks on the sea floor because the rocks on the continents are not being removed unlike the rocks on the sea floor that are made by the mid-ocean ridge are being removed by deep ocean trenches. this prossess that is occuring on the sea floor is called sea floor spreading. evidence of this is the Pacific ocean shrinking and the Atlantic ocean growing.
Which geologic process forms new crust on the ocean floor?
seafloor speading
How would the age of the oldest rock on the continents compare with the age of the oldest rock on the seafloor?
The sea floor is young (the rocks are made at the mid oceanic ridges and spread out form there) while most of the continental rocks are older. This is because the continental crust floats on top of the oceanic crust and is therefore not recycled.
What is this is the process of creating new oceanic crust?
Sea floor spreading
What is the process in which new sea floor forms as other older sea floor is pulled apart?

What is the age of the oldest seafloor?
The oldest seafloor is estimated to be around 200 million years old. New oceanic crust is continuously formed at mid-ocean ridges, so the seafloor is constantly being recycled.
What ocean-floor feature is associated with areas where oceanic crust is broken down?
The mid ocean ridge is the area of the ocean floor that is associated with the breaking down of the oceanic crust. This area is known for seafloor spreading.
What is seafloor mining?
Mining on the sea floor, are you dumb?
Where do you find young seafloor?
in the depths of the oceanic crust floor.

Why is the earth 4.6 billion years old but the oldest sea floor is only 180 millions years old?
Just as new sea floor forms at mid-ocean ridges, new sea floor is forced back into the mantle at abduction zones. The oldest seafloor is at east and west the edges of the Atlantic Ocean, dating to the breakup of Pangaea.

The bottom of the ocean is called?
The bottom of an ocean is typically called the seafloor. Although the seafloor can have variant geographical features such as mountains or volcanos, a normal, and flat terrain is called the seafloor.
