The rocks off of the east coast of North America are much older than those right along the mid-Atlantic ridge because sea-floor spreading is occurring where oceanic plates are diverging from one another. The rocks right along the ridge are the newest ones being formed, and the ones off the east coast of North America were formed a long time ago.
The rocks off the east coast of North America are about the same age as the Earth, 4.6 billion years. The rocks close to the mid-Atlantic ridge are much newer as they are being formed at this divergent boundary right now.

The rocks on the Mid Atlantic Ridge are among the youngest. The moment the magma that is being produced there cools enough to solidify, it becomes an igneous rock.
The rock of the Atlantic Ocean seafloor is less than 200 million years of age on the oldest end, and currently in the process of creation at the Mid-Atlantic Ridge.

Rocks on the sea floor are very young because most have resulted from recent volcanic activity. Volcanic activity is constantly erupting on the ocean's floor and creating new rocks.
Mid-atlantic ridge
On each side of the mid-ocean ridge is a mirror of the striped pattern on the other side. When drawn, these patterns show alternating bands of normal and reverse polarity that match the geomagnetic reversal time scale, scientists can assign ages to the sea-floor rocks. The youngest rocks were at the center, and the older rocks father away. The ages of the sea floor rocks are symmetrical. The only place on the ocean-floor where new rocks are formed are at the rift in mid-ocean ridge. hope this helps :)
Perpendicular (away from) the ridge, that why the Atlantic ocean is widening.

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.
Around 200 million years of age.
Forms by lava from volcanoes on the sea floor
The prominent sea floor feature found in the central Atlantic ocean is called the Mid Atlantic Ridge.

Closest to the ridge
new rocks form
Rocks have a north and south pole. The sea floor was discovered to have different magnetic poles on cracks in the ocean floor.
