现在刚建立一种新型地球内部图象。在20世纪初,有人认为地球是由坚硬、凝固的地壳构成。现有知识告诉我们,地球内部的巨大质量处于不停的运动之中。在地核和地壳之间,循环流动的岩浆隆起和下降可达数千米。岩浆流到地壳缝隙处,为了向上冲出地壳,岩浆下降到地核前的海洋地壳断裂处,这时岩浆在地下深处开始推动移动的大陆。最近几年进行的一系列实验丰富充实了地球内部图象,但是它仍然还不完整。
Now a new type of Earth’s interior image has just been established. At the beginning of the 20th century, some thought that the Earth was composed of a hard, solidified crust. Current knowledge tells us that the great quality of the Earth’s interior is constantly moving. Between the earth’s core and the earth’s crust, circulating magma uplift and descent of up to several kilometers. The magma flowed into the crustal crevices, and in order to break out of the crust upward, the magma descended to the crust of the oceanic crust before the earth’s core, when the magma started to push the moving continent deep underground. A series of experiments conducted in recent years have enriched the images inside the Earth, but it is still incomplete.
