In cylindrica l folds the crest and trough lines are parallel. to the fold axis and to each other, but in conical folds the crest and trough lines are not. parallel. Crest and trough surfaces connect the crest and trough lines on successive. horizons.
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.
