1. You have to understand the earth, the earth is divided into the crust (Qiao), mantle, core, the center of the earth is the core, it is a high density iron ball, this is not difficult. The difficulty is the asthenosphere in the mantle (boiling magma, let's say so for a moment), ultra-high temperature and ultra-high pressure. General steel melts directly for you, but special materials with high melting point may also be directly pressed into metal blocks. And there's a thick layer of rock above it. Recommend to see the movie "the destruction of the center of the earth", also called "the rescue of the center of the earth"
2. Hang up method: press the "home" key directly to jump to the main interface to hang up. Other operations at this time will not affect the operation of digging to the center of the earth.
3. Diamonds get the most from their achievements, but the later they get, the slower they get. It's just luck to get diamonds by digging. The probability of digging a treasure box is higher than that of diamonds. There's a bonus for the United buildings! Give priority to high-grade buildings as far as possible! It's fast to dig money. It's upgrading low-grade buildings
4. Go to knight mobile assistant to have a look, there are many cracking games and software on it.
5. If he doesn't give you a refund, it's likely that there are some illegal aspects of the software. You can report it to the official platform.
6. The natural environment will change! It's just that it's hard for human beings to notice the changes in the natural environment. For example, how about the sense of smell of people and dogs? What about the gravitational waves of mice and elephants? This shows that the environment is changing. It's just as hard for human beings to perceive that it didn't rise by 0.5 degree in 1200. There have been several ice ages on the earth. I think it has a lot to do with the earth, the sun and the center of the galaxy. For example, if the earth revolves around the sun in spring, summer, autumn and winter, and the sun revolves around the center of the galaxy, is there spring, summer, autumn and winter
the earth has no real "weight" because it is not fixed on a particular planet or surface. It does have mass because it has a certain amount of material. Here, I think you're asking if the mass of the earth can change. Because matter cannot be created or destroyed, the only way to change the quality of the earth is for new matter to enter the earth, or for matter to leave the earth! We usually think that the mass of the earth is constant. Many times we think this is correct. But if we try to do better, the mass of the earth is actually decreasing! The earth gains mass from st and meteorites that gravity grabs. If you've seen the recent meteor shower, you'll find that it happens a lot. According to satellite observations of meteor trajectories, about 100 to 300 tons of material hit the earth every day. About 30000 to 100000 tons per year
7. Balta, a Hungarian scientist, put forward an interesting theory: the heart of the earth is not in the geometric center of the earth, but hundreds of kilometers away from the geometric center. The heart of the earth moves along an elliptical path at a speed of one kilometer a year. This theory can be used to explain the difference of gravity and the reason for the graal change of gravity around the earth, The international geophysical Commission (IGC) has decided to set up 15 geophysical stations along the equatorial region to form an observation network@ Qi wending, Hungarian scientist Balta put forward an interesting theory that the heart of the earth is not in the geometric center of the earth, but hundreds of kilometers away from the geometric center. The heart of the earth moves along an elliptical orbit at a speed of one kilometer a year. This theory can be used to explain the differences in gravity and the reasons for the graal change of gravity around the earth
