The Mid-Atlantic Ridge is neither Continental rock or indeed the oldest rock on the planet. The rock in the ridge is commonly the youngest, or of the youngest, on the planet, as it was formed most recently, and is oceanic, not continental, crustal rock.
The oldest rock in oceanic crust is that which is found the greatest distance from a mid-ocean-ridge.
The Mid-Atlantic Ridge is part of the greater mid-ocean ridge system, an underwater mountain range that is over 40,000 miles long. The age of new rock closest to the ridge would be roughly the same anywhere along the ridge.
Near the mid-Atlantic ridge.
There is a mid-Atlantic trench in the Earth that is below the mid-Atlantic Ocean.

There is a mid-Atlantic trench in the Earth that is below the mid-Atlantic Ocean.
The Atlantic Ocean has the mid-ocean ridge which has lava flow about every year and pushes out the rock around it. The Atlantic ocean expands about two inches every year pushing the continent with it.
The Mid-Atlantic Ridge is predominantly made up of basaltic rock, which is formed from cooled lava. This type of rock is common in oceanic crusts due to volcanic activity along divergent plate boundaries where tectonic plates are moving apart.
why was the mid atlantic colonies founded
Rock formed at the mid-Atlantic ridge can be uplifted through tectonic processes and exposed to weathering and erosion. The eroded rock particles can then be transported by rivers or wind and eventually deposited in a basin, where they can accumulate over time to form sedimentary layers. Through compaction and cementation, these layers can then lithify into sedimentary rock.
