地球上火山喷出的熔岩温度高达1200℃~1300℃,天然温泉的温度大多在60℃以上,有的甚至高达100℃-140℃。这说明地球是一个庞大的热库,蕴藏着巨大的热能。那么地热是从何而来的呢？ 这就需要从地球的构造谈起。地球可以
The temperature of volcanic lava on the earth is as high as 1200°C to 1300°C. Natural hot springs are mostly at temperatures above 60°C, and some even reach 100°C to 140°C. This shows that the Earth is a huge heat pool and contains huge heat energy. So where did the geothermal come from? This requires talking about the structure of the earth. Earth can
