Peculiarities of a space distribution of the mid-oceanic ridge volcanism are examined. Volumes of an entrance of volcanic material are calculated and rates of the ocean-floor spreading are determined for every mid-oceanic ridge, depending on geographical latitude. The analysis of the received material shown of submarine volcanic activity dependence not only from poles of rotation lithospheric plates, but also from of rotation of the Earth.
