The mechanism by which new seafloor is created along the rift at the crest of a mid-ocean ridge as adjacent plates move apart. 8, record 1, English, - seafloor%20spreading
Record number: 1, Textual support number: 1 OBS
The crust separates along the rift, and new seafloor forms as hot new crust upwells into these cracks. The new seafloor spreads laterally away from the rift and is replaced by even newer crust in a continuing process of plate creation. 8, record 1, English, - seafloor%20spreading

La croûte se déchire le long du rift et il se forme un nouveau fond marin alors que de nouveaux matériaux de croûte chauds s’élèvent dans les fissures. Le nouveau fond marin s’étale latéralement de part et d’autre du rift et est remplacé par de la croûte encore plus récente dans ce processus ininterrompu de création de plaque. 6, record 1, French, - expansion%20oc%C3%A9anique

Volcanic margins occur where very voluminous magmatism accompanies rifting and ocean seafloor spreading occurs right after continental breakup. ... The only regional geophysical data set available in those areas is aeromagnetic mapping that does not clearly show a well defined pattern of linear seafloor-spreading magnetic anomalies as that observed in pristine ocean lithosphere of large ocean basins like the Atlantic. 6, record 2, English, - oceanic%20spreading%20anomaly

En 1961, Robert Dietz [...] introduisit l'expression «sea floor spreading» (expansion des fonds océaniques). En 1963, Lawrence Morley, Fred Vine et Drumond Matthews confirmèrent les idées de Hess et de Dietz en interprétant les anomalies magnétiques découvertes sur le plancher océanique comme des marqueurs de l'expansion. Ces anomalies formaient des bandes alternativement positives et négatives, disposées parallèlement et symétriquement par rapport aux dorsales. 2, record 2, French, - anomalie%20de%20l%27expansion%20des%20fonds%20oc%C3%A9aniques

En mer, les anomalies magnétiques marines qui sont parallèles aux dorsales ont permis de démontrer que l'expansion des fonds océaniques, c'est-à-dire que le plancher océanique se forme aux dorsales et s'en éloigne en se refroidissant. Sur les continents, les anomalies magnétiques permettent de mettre en évidence des grandes structures dans la croûte continentale. 3, record 2, French, - anomalie%20de%20l%27expansion%20des%20fonds%20oc%C3%A9aniques
