Mid-Ocean Ridges
a ridge in the ocean
Divergent boundaries form ocean ridges.
Magnetic alignment of rocks, in alternating strips that run parallel to ridges, indicates reversals in Earth's magnetic field and provides further evidence of seafloor spreading.

Mid-Ocean Ridges
Definition: Fine ridges on a fracture surface, parallel to the direction of propagation of the fracture. source: About.com
Lateral moraines are parallel ridges of debris deposited along the sides of a glacier
sand ridges that rise slightly above the surface of the sea and run roughly parallel to the shore, from which it is separated by a lagoon.
Linear, magnetic patterns associated with mid-ocean ridges are configured as normal and reversed magnetized strips roughly parallel to the ridge. A very long lived magma source located deep in the mantle is called a hot spot.
You may be thinking of pavé setting.
It is a ridges of sediment that accumulate along the margins of river channels on floodplains.
