一种假说认为:在地球漫长演化史中,超级大陆的形成对地球氧气起源也起到了至关重要的作用:随着超级大陆的形成,陆地面积变大,地壳侵蚀作用加大,火山性质发生变化(火山喷发更多发生在陆地而非水下),这些地质变化与海洋里的蓝藻一起,促使地球大气出现了更多氧气。 One hypothesis holds that the formation of the supercontinent also plays a crucial role in the origin of the Earth’s oxygen during the long evolution of the Earth: with the formation of the supercontinent, the land area becomes larger, the crustal erosion increases, and volcanic properties occur Variations (where volcanic eruptions occur more on land than underwater), together with cyanobacteria in the oceans, contribute to the creation of more oxygen in the earth’s atmosphere.
