经常听到同学们提出这种好奇的问题:我们生活在地球上,一天天地长大,地球是不是也在长大呢?匈牙利的物理学家拉斯诺·爱德耶特经过长期的研究后宣布,地球没有缩小,相反,它的体积还在不断扩大。拉斯诺·爱德耶特教授说:地球的外壳是由地壳形成的,地壳下面是中间层,中间层里是由核壳和核心组成。中间层、核壳和核心的成分是一样的,都是由各种含硅(石头)的物质组成,只是密度不同。核内的密度最大。核心密度大的物质不断渗透到核壳中,而壳中的物质又不断渗透到中间层。这样,它们的密度就变小了。所以,地球的平均密度总是在不断地减少,那么,地球的体积也就随着不断地扩大了。
He often heard the students raise this curious question: We live on the earth and grow up day by day. Is the earth growing up? Hungarian physicist Rasno Ayyet went through long-term research After the announcement, the earth did not shrink. On the contrary, its size is still expanding. Professor Rasnoy Adjeet said: The Earth’s outer shell is formed by the earth’s crust. Below the earth’s crust is the middle layer. The middle layer is composed of core shell and core. The composition of the middle layer, the core shell and the core is the same, and it consists of various materials containing silicon (stone) but different densities. The density is highest in the nucleus. The core dense material continuously penetrates into the core and shell, and the material in the shell continuously penetrates into the middle layer. In this way, their density becomes smaller. Therefore, the average density of the Earth is constantly decreasing. Then, the size of the Earth will continue to expand.
