Webb27 mars 2024 · The spreading rates of mid ocean ridges may be 2-3 cm per year. A mid ocean ridge has a steeper and more irregular topography as a result of a low spreading rate. The ridge consists of a high central axial zone, with a narrow crest. The mid ocean ridges and rises are offset by rugged fault scars called fracture zones.

Webb5 feb. 2012 · A fundamental long standing problem of plate tectonics is how the orthogonal ridge transform fault pattern typical of spreading oceanic ridges has formed and why it is maintained. The large time scales involved in the evolution of this pattern on the Earth prohibit real time observation.

The low axial topography at the 22-23"N area can be explained by the existence of a low fridge rs253baww samsung price
