We don’t know for sure what’s under our earth’s crust but this theory completely forgets to mention where the magma that erupts from volcanoes comes from if the earth is hollow.
我们至今仍然不知道地壳之下是为何物，但是这个理论遗漏了一个问题：如果地球是空心的，那么火山喷发而出的那些岩浆来自何处？
He said the widely accepted theory that when a volcano's magma chamber cools it could be years before it heats up with fresh magma could be wrong.
他声称，之前普遍为大众接受的理论可能是错的——即当火山岩浆库冷却后，需要经过多年才能在新岩浆的作用下重新恢复高温。
Use geo-anomalous theory to study of the geology, structure and magma complexity for region, final for the integrallty geological complex maps.
运用地质异常理论，对研究区内地层、构造和岩浆岩进行地质复杂度研究，并最后获得该区域综合地质复杂度图。
