There are 31 articles in this book. Among them, "Looking at the Universe from the Earth" is the article that interests me the most. It makes us seem to see the vastness of the universe. The universe we see now is only a small part of it, and there is still a large part waiting for us to explore. In this huge cosmic space, there are still many materials scattered, and the earth is just an extremely small member of their big family. Some of them are still growing, some have grown to a certain stage, and some have grown to a certain stage. is disappearing...
After reading the article "Geothermal", I was a little shocked. It tells us that from the surface of the earth to its depths, the temperature will rise higher and higher. Data records: Asia generally rises by 1°C at around 40 meters, Europe generally rises by 1°C at 28 to 36 meters, and North America generally rises by 1°C at 40 to 50 meters. Wow! If we assume that the ground temperature increases by 3°C for every 100 meters of depth, then just go 40 kilometers down and the temperature will reach 1200°C.
