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 ...
Ridge Types. There are two types of mid-ocean ridges: fast-spreading and slow-spreading. Fast-spreading ridges like the northern and southern East A composite map showing the topography (relief) of the ocean floor clearly reveals the mid-ocean ridge system, which appears here as dark "seams"...
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 ...
The mid-ocean ridge is the world's longest continuous mountain range, stretching over 65,000 kilometers (40,000 miles) across the globe. Loc...
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.
Mid-ocean ridges (MORs) are quintessential sites of tectonic extension1–4, at which divergence between lithospheric plates shapes abyssal hills that cover about two-thirds of the Earth’s surface5,6. Here we show that tectonic extension at the ridge axi
Mid-ocean ridges are constructive plate boundaries where new crust is created. In map view, the system resembles a stair-step configuration of alternating spreading ridges and ridge offsets. Some ridges and offsets, typically large ones, remain fixed and maintain their plan-view shape over many ...
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...
