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 ...
大西洋洋中脊(又称大西洋中洋脊;英文:Mid-Atlantic Ridge)是一个大部分地区位于海底的山脉,横跨大西洋及北冰洋。大西洋洋中脊由北纬87度(距离北极333公里)伸延至南纬54度的布韦岛。大西洋中脊的最高点突出海面,形成海岛。大西洋洋中脊为全球洋中脊(Mid-ocean ridge)系统的一部分,其形成方式亦被认为与其他洋中...

Fission-track dating of basaltic glass from the Mid-Atlantic Ridge gives results which are consistent with the proposal of ocean-floor spreading. Solidification ages from 10,000 years to 300,000 years were measured. Correlation is also possible between the magnetic anomaly patterns over the Crest ...
