How old is oceanic crust in the Atlantic Ocean?

Where are the oldest parts of the Atlantic Ocean?
The oldest oceanic crust in the Atlantic is up to 145 million years and situated off the west coast of Africa and east coast of North America, or on either side of the South Atlantic.
Where the oceanic is crust the oldest Why?
New ocean crust is formed at the mid ocean ridges. The new crust is then pushed away from the ridge as newer crust comes to the surface. The ocean crust then spreads out enlarging the ocean. The farer away from the ridge the ocean crust is the older the crust is.
What is the oldest known oceanic crust?
Herodotus Basin is thought to be 340 million years old Now, this region, called the Herodotus Basin, has been shown to be 340 million years old—the oldest ocean crust on Earth that remains under the sea, according to a study published online today in Nature Geoscience .
Where are the oldest rocks in the Atlantic Ocean?
The next oldest seafloor is found at the margins of the north Atlantic Ocean and the northwestern Pacific Ocean, as far as possible from the mid-ocean ridges where they were created. These parts of the seafloor are about 200 million years old. Age of the oceanic crust. Courtesy of NOAA.
Where are the oldest rocks in the Atlantic found?
The earth's oldest rocks are found along the Mid-Atlantic Ridge. The theory of plate tectonics states that the earth's crust is made up of a single massive plate. The Mid-Atlantic Ridge is an example of a divergent plate boundary.
