地壳,在茫茫的星海中是一处十分珍贵的宝地。它不仅孕育了生命,还是一个巨大的载体,承载着无数种生物繁衍生息和进化发展。此外,还拥有种类繁多的矿产资源,以供人类享用。地壳的这些功能是显而易见、众所周知的。在人们习以为常的尽情享受中,却往往忽视了地壳的另一个主要功能——封堵地球内部的巨量热能。由于地球具有距太阳的距离最适中、公转和自转速度又恰到好处的两大优势,天生注定了它的深部将长久地呈现熔融状态,从而蕴藏着巨最热能。现代地壳底部的温度约400—1000℃,地幔温度在1100—4300℃之间,地核温度则高达4400—6000℃。由此可知,地壳
The crust, in the vast Xinghai is a very precious treasure. It not only gave birth to life, but also a huge carrier, bearing innumerable species multiply and evolve. In addition, there are a wide variety of mineral resources for human enjoyment. These functions of the crust are obvious and well known. In the common enjoyment of people, one often overlooks the other major function of the earth’s crust - the massive heat trapped inside the Earth. Since the Earth has two major advantages of being the most moderate in distance from the Sun and revolving at the right rotation speed, it is inherently destined that its deep part will assume a long-term melting state, thus holding the gigantic heat. The temperature of the bottom of the modern crust is about 400-1000 ° C, the mantle temperature is between 1100-4300 ° C, and the core temperature is as high as 4400-6000 ° C. This shows that the crust
