A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the ...

The speed at which new ocean floor is created varies from one location on the ocean ridge to another. Between North America and Europe, the rate is about 2.2 inches (3.6 cm) per year.

Dick says that the ultraslow ridges account for 12,000 miles of the total 30,000-mile mid-ocean ridge system. ... Since the acceptance of continental drift and plate tectonics in the early 1960 ...

Plate tectonics has its own version of the circle of life. Outlined by geologist J. Tuzo Wilson, the Wilson Cycle describes the birth and death of the ocean basins that separate continents.

The Mid-Atlantic Ridge (MAR) is a mostly underwater mountain range in the Atlantic Ocean that runs from 87°N -about 333km south of the North Pole- to subantarctic Bourvet island at 54°S. The MAR is ...

The Mid-Atlantic Ridge, particularly in the South Atlantic, also may have direct coupling with deep mantle flow, he added. “The consequences of this research are very important for all scientists ...

The Atlantic Ocean is currently getting wider at the mid-Atlantic Ridge, a divergent plate boundary that pushes the Old and New Worlds apart at a rate of around 2.5cm per year.
