There is a catastrophic natural disaster on our planet - the big **. It can cause us great destruction and suffering. Even the most powerful ** will not be able to completely destroy our planet. Why is that?
We need to understand a basic concept – the earth is self-healing. Its rock layers, soils, and atmosphere are constantly undergoing natural changes and renewals. Even a huge volcanic eruption or a strong ** will not completely change the process. For example, after a volcanic eruption, although the ground is severely damaged, new crust forms over time to fill the gap, and these new crusts become more stable over time. Again, after that, cracks will be created in the surface, but this will not make the whole planet incomplete, but it will make the terrain richer and more diverse.
What if it was feasible to let the planet "commit suicide"? The answer is absolutely not. The reason for this is that the internal structure of the Earth contains a large number of radioactive elements, which release large amounts of energy during the decay process. This energy is sufficient to maintain the temperature of the Earth's core and keep the Earth's core in a liquid state, which in turn triggers a magnetic field that protects life on Earth from solar storms. Without the heat and gravity in the core, the Earth would gradually cool and shrink into a fire-like giant (a much smaller body than it is now but still possessing massive mass), which would lead to the disappearance of all life forms, including humanity itself.
The fate of the other type of star, the white dwarf, is much more tragic. When a medium-sized star runs out of fuel and becomes a red giant, its outer layer will be shaken off due to its gravity, leaving only the core to continue burning. Once the hydrogen in the core area is burned out, it goes into the so-called"Helium flash phase"。During this phase, the white dwarf begins to expand rapidly and heat up. When the reaction stops, the external gas redeposits on the surface of the white dwarf, causing another **increase in its brightness**, which is called a supernova**.
Neither the serious** nor other forces that could pose a threat to the planet could make it die permanently. This is because the Earth has a strong self-healing capacity and a unique survival mechanism. Another type of star, such as the white dwarf, is prone to destruction due to its extreme state and evolutionary process. While admiring the beauty and spectacle of the earth, we should also cherish and protect this place that provides us with a home.
