Mid-ocean Ridges

2010
Mid-ocean ridges are the oceanic counterparts of continental graben structures. Both are zones of extension although mid-ocean ridges have substantially higher spreading rates and also mark plate boundaries where new oceanic crust and lithosphere are formed.

Mid‐Ocean Ridges

2004
Two thirds of our planet are covered by ocean, beneath which stretches basaltic oceanic crust. The eruptions that produce this crust are hidden from direct observation. Remote sensing instruments with which to record the countless volcanic eruptions that occur under the ocean waves each year are few and far between. Even the fact that mid-ocean ridges (

The Mid-Ocean Ridge

Scientific American, 1990
The Mid-Ocean Ridge girdles the earth like the seam of a baseball. For more than 75,000 kilometers, this submerged range of razorback mountains--many higher than the greatest peaks on land--marks the restless boundary between continental plates. An analysis of this huge structure reveals a fascinating picture of how it is created by magma welling up as

Mid-ocean Ridges

2017
Mid-ocean ridges illustrate well how volcanic, tectonic, hydrothermal and sedimentary processes sculpt geomorphology in the deep ocean. Because of their poor accessibility (lying 2700 m below sea level on average) and remote locations, the development and deployment of new technology has been important for the discovery and investigation of new ...

Mid-ocean ridges

2007
A map of the ocean basins (Fig. 5.1) shows that their most conspicuous topographic feature is the system of mid-oceanic ridges, the crests of which rise on average 1000–3000 m above the adjacent ocean floor. Such ridges extend through all the major ocean basins, with a total length in excess of 60 000 km.
