Why Is The Center Of The Earth Hot
Camila Farah
The vast majority of the heat in the earth s interior is generated by radioactive decay.
In truth we need the planet s center to remain blistering hot so that it can protect earth from potentially harmful solar winds and debris. You might be wondering why is the center of the earth so hot well it s the combination of two things. First all the radioactive materials in the earth generate heat as they decay. The heat from when the planet formed the heat from the decay of radioactive elements.
The interior of earth is very hot the temperature of the core reaches more than 5 000 degrees celsius for two main reasons. Part of this energy is why the center of the earth is hot. Earth is actually really bad at getting rid of heat so much of the primordial heat from when the core first developed has been retained. The melting temperature of iron under deep earth.
That s when the planet first formed from a cloud of gases and particles. But if new findings are correct then the center of our own planet may actually be hotter. The earth was formed by the process of accretion. So why is the center of the earth hot.

Total heat produced by the earth s radiation is the same as the heat measured emanating from the earth. It is believed that when earth was created over billions of years there were actually large chunks of asteroids and planetary objects hitting each other from the explosion. It s been that way since oh about 4 5 billion years ago. Not all planets have a center or core that is hot.
The next source is gravitational pressure put on. The bottom line here is simply that a large part of the interior of the planet the outer core is composed of somewhat impure molten iron alloy. The answer comes from a lot different sources. In new research scientists studying what the conditions at the core should be like found that the center of the earth is way hotter than we thought around 1 800 degrees hotter putting the.
