The sea floor is spreading away from the mid-ocean ridges.
海底正在從大洋中脊擴張開來。Through the systematic analysis and contrast studies on topographical environment characteristics of these typical regions, it is found that the hydrothermal activity only occurs under the circumstance of the particular topographical environment, though it distributes widely in the tensional tectonic environment, for instance, the mid - ocean ridges, transform faults zones, back - arc spreading basins and the modern marine craters regions
通過對典型熱液區地形環境特徵的系統分析和對比研究發現盡管現代海底熱液活動廣泛分佈在大洋中脊、轉換斷層、弧后擴張盆地等各種不同的張性構造環境及現代海底火山活動區,但也僅出現在特殊的地形環境條件下。The mariana trough is an actively opening back arc basin that lies at the eastern edge of the philippine sea plate, and in the transition time from rift to sea floor spreading
位於菲律賓板塊和太平洋板塊之間的馬里亞納海槽,處于弧后張裂向海底擴張的過渡階段,是深入研究板塊運動與弧后擴張動力學過程的理想地區。The rifts therefore represent divergent plate boundaries where seafloor spreading is taking place
這樣,大洋中脊就成為板塊分離邊界,海底擴張就發生在這里。分享友人
