WebSep 2, 2024 · What 2 types of faults are found along the Mid-Atlantic Ridge? Every 50-500 km, the mid-ocean ridge is offset sideways right or left by transform faults (found where two plates slide sideways against each other). The ridge also has many smaller lateral offsets which, together with larger transform faults, divide the mid-ocean ridge into many ... WebJun 27, 2024 · Mid-ocean ridges do not form straight lines but are instead offset in many places by fracture zones, or transform faults. Fracture zones are thought to occur due to zones of weakness in the pre-existing continent before it was rifted apart. Most mid-ocean ridges are divided into hundreds of segments by fracture zones.
WebThe crust along a mid-ocean ridge is younger than crust farther away. Volcanoes are less likely to result in changes along mid-ocean ridges than in other parts of an ocean basin. Converging tectonic plates force land-forming magma up through the ocean floor to …
WebDivergent boundaries are typified in the oceanic lithosphere by the rifts of the oceanic ridge system, including the Mid-Atlantic Ridge and the East Pacific Rise, and in the continental lithosphere by rift valleys such as the famous East African Great Rift Valley. Divergent boundaries can create massive fault zones in the oceanic ridge system. WebA mid-ocean ridge (or mid-oceanic ridge) is an underwater mountain range, typically having a valley known as a rift running along its axis, formed by plate tectonics. This type of oceanic ridge is characteristic of what is …
