What is happening in the middle of the Atlantic Ocean?
The Mid-Atlantic Ridge includes a deep rift valley that runs along the axis of the ridge along nearly its entire length. This rift marks the actual boundary between adjacent tectonic plates, where magma from the mantle reaches the seafloor,
erupting as lava
and producing new crustal material for the plates.
