The Galapagos Rise is a divergent boundary located between the South American coast and the triple junction of the Nazca Plate, the Cocos Plate, and the Pacific Plate. The volcanically active Galapagos Islands exist on a hotspot above the Galapagos Rise. The Galapagos Microplate is a small separate plate on the rise just to the southeast of the triple junction. ...more on Wikipedia about "Galapagos Rise"
Lomonosov Ridge (Хребет Ломоносова in Russian) is an underwater oceanic ridge in the Arctic Ocean. It spans for 1800 km from the New Siberian Islands over the central part of the ocean to the Ellesmere Island of the Canadian Arctic islands. The width of the Lomonosov Ridge varies from 60 to 200 km. It rises 3,300 - 3,700 m above the seabed. The minimum depth of the ocean above the ridge is 954 m. Slopes of the ridge are relatively steep, broken up by canyons, and covered with layers of silt. ...more on Wikipedia about "Lomonosov Ridge"
The Mid-Atlantic Ridge is a mostly underwater mountain range of the Atlantic Ocean that runs from 87°N (about 333 km South of the North Pole) to subantarctic Bouvet Island, where it turns into Atlantic-Indian-Ridge and continues further East through Crozet Plateau to the Southwest Indian Ridge, while in the West it is followed by Scotia Ridge. It is part of the mid-oceanic ridge. The highest peaks of this mountain range extend above the water mark, to form islands. Near the Equator, the Mid-Atlantic Ridge is dissected into the North Atlantic Ridge and the South Atlantic Ridge by the Romanche Trench, a narrow submarine trench with a maximum depth of 7 758 m, one of the deepest locations of the Atlantic Ocean. The portion of the ridge north of Iceland is in fact part of the Arctic Ocean. The islands are, from North to South, with their respective highest peaks, elevations in m, and location: ...more on Wikipedia about "Mid-Atlantic Ridge"
An oceanic ridge is an underwater mountain range, formed by plate tectonics. The mid-ocean ridge system is the longest mountain range in the world, whose total length is ~60,000km. ...more on Wikipedia about "Oceanic ridge"
The Pacific-Antarctic Ridge is an oceanic ridge at the boundary between the Pacific and Antarctic Plates. Convection currents in the Earth's mantle are causing the plates to separate, creating new oceanic crust at a rate of approximately 3cm each year. ...more on Wikipedia about "Pacific-Antarctic Ridge"
