Oceanic crust is created at mid-ocean ridges and (through the creation of new oceanic crust) is pushed toward a convergent plate boundary where it is subducted. So the oldest oceanic crust would be located at a convergent plate boundary where the oceanic crust is being subducted under continental crust.

Why are the oldest parts of the ocean floor no older than about 200 million years.?
Because the oldest parts reach the continental crust and then the ocean floor sinks beneath the continental crust, into the mantle.
During which era could parts of the ocean floor have formed?
mesozoic
What are Isolated volcanic peaks on the ocean floor known as?
Isolated volcanic peaks on the ocean floor are known as seamounts. The deepest parts of the ocean are long, narrow features known as deep ocean trenches.
What are offshore trenches?
Offshore trenches, also known as oceanic trenches, are depressions in the sea floor. They are the deepest parts of the ocean floor.
What are the five ocean basins?
Parts of the ocean sea floor are:trenchessea mountsabyssal plaincontinental shelf and slopevolcanic islandsmid ocean ridge
What is the three parts of the ocean floor that are located near the coast?
Intertidal zone
What are the three parts of the ocean floor that are located near the coast?
Intertidal zone
What do we call the central ridge that divides the ocean floor into two parts?
It is the mid-ocean ridge.
Why are the oldest parts of the ocean floor no older than about 200 million years.?
Because the oldest parts reach the continental crust and then the ocean floor sinks beneath the continental crust, into the mantle.
During which era could parts of the ocean floor have formed?
mesozoic
Can plated carry continents or parts of the ocean floor but not both?
Tectonic Plates can't carry both ocean floor and continents on the same plate.
What are Isolated volcanic peaks on the ocean floor known as?
Isolated volcanic peaks on the ocean floor are known as seamounts. The deepest parts of the ocean are long, narrow features known as deep ocean trenches.
What are the 4 parts of the ocean floor?
Pacific Ocean, Artic Ocean, Atlantic Ocean, and the Indian ocean. im ten years old. that's so easy.
What is an oceanic trench?
An ocean trench is a deep canyon in the ocean floor that forms at a destructive plate margin where oceanic crust flows back into the Earth's mantle. An example would be the Mariana Trench is the deepest point in any ocean and is located in the Pacific Ocean
What is the underwater volcanic mountains that divide the ocean floor into two parts?
volcanic mountains not formed on mid-ocean ridge
As the ocean floor spreads other parts plunge into the mantle What is this process called?
subduction
IF the ocean floor spreads other parts plunge into mantle this process is called?
Subduction .
