Why Is The Center Of The Earth Hot
Camila Farah
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.
Part of this energy is why the center of the earth is hot. The vast majority of the heat in the earth s interior is generated by radioactive decay. 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. The melting temperature of iron under deep earth.
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. First there is heat left over from when the planet formed and accreted. The answer comes from a lot different sources. First all the radioactive materials in the earth generate heat as they decay.
The first is heat left over from the formation of the earth. The earth s inner core has three main sources of heat. The earth was formed by the process of accretion. The heat from when the planet formed the heat from the decay of radioactive elements.

The next source is gravitational pressure put on. As each one crashed into another energy was produced making the center hotter and hotter. That s when the planet first formed from a cloud of gases and particles. The interior of earth is very hot the temperature of the core reaches more than 5 000 degrees celsius for two main reasons.
Not all planets have a center or core that is hot. Total heat produced by the earth s radiation is the same as the heat measured emanating from the earth. It s been that way since oh about 4 5 billion years ago. You might be wondering why is the center of the earth so hot well it s the combination of two things.
