似乎有些不可思议,但是地球生命活动的各种侵蚀却促进了陆地面积的增长。研究者在欧洲地球科学联合会(European Geosciences Union)年会上说,生命活动改变了陆地面积。根植于岩石的地球生命,将岩石侵蚀粉碎为沉积物。这些沉积物如同浸入牛奶的饼干,携带液态水进入洞穴,使更多的水回到地幔重新参与循环。100~200千米深的地幔如果没有足够的水保持物质流动,产生的陆地将少于现在。论文作者建立的行星演化模型表明,在维持很大的陆地面积时,如果陆地风化和侵蚀率下降,这一
It seems incredible, but all kinds of erosion of the life-activity of the Earth have promoted the growth of land area. Researchers at the annual meeting of the European Geosciences Union said that life activities have changed the land area. The life of the earth, rooted in rocks, crushes the rocks to sediment. These deposits, like crackers dipped in milk, carry liquid water into caves, returning more water to the mantle to re-circulate. The mantle, 100-200 km deep, will have less land than it does now, if it does not have enough water to keep the material flowing. The planetary evolution model established by the authors shows that, in the event of a large land area, if the rate of weathering and erosion on the land decreases
