The plates on either side of the Mid-Atlantic Ridge are spreading apart from each other at a rate of 2.5 centimeters per year. Where is the Mid-Atlantic Ridge? This topographical map shows the map of the ocean floor. The Mid-Atlantic Ridge can be seen running north-south in the middle ...

Map of the global mid-ocean ridge system on the ocean floor, NOAACentral rift valleys & plate movementRift valleysThe youngest rocks on the ocean floor are located in the rift valleys where magma pushes up the crust as it move from the upper mantle to vents on the ocean floor. The ...
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 ...

Learn the mid-ocean ridge definition and see a mid-ocean ridge example. Find out what causes mid-ocean ridges and what happens at a mid-ocean ridge.
During Leg 209, 19 holes were drilled at 8 sites along the Mid-Atlantic Ridge from 14°43′ to 15°44′N, mainly in residual man- tle peridotite intruded by gabbroic rocks, in order to understand the tectonic and structural processes responsible for formation of oceanic lithosphere with ...
mid-o·cean ridge (mĭd′ō′shən) A long mountain range on the ocean floor, extending almost continuously through the North and South Atlantic Oceans, the Indian Ocean, and the South Pacific Ocean. A deep rift valley is located at its center, from which magma flows and forms new o...
A composite map showing the topography (relief) of the ocean floor clearly reveals the mid-ocean ridge system, which appears here as dark "seams" extending through the oceans. In the Atlantic Ocean, the mid-ocean ridge is called the Mid-Atlantic Ridge. It curves from the Arctic Ocean southw...
Magnetization of 0–29 Ma ocean crust on the Mid-Atlantic Ridge, 25°30′ to 27°10′N A sea-surface magnetic survey over the west flank of the Mid-Atlantic Ridge from 0 to 29 Ma crust encompasses several spreading segments and documents the ... Maurice,A.,Tivey,... - 《Journal of...
