It extracts that from the radioactive decay of a number of long-lived isotopes of uranium, thorium, potassium and a few more.These isotopes were once formed in a supernova explosion and not yet completely extinct.
And no this is not at all beyond what laws of thermodynamics as well.
The contrary happens!The core is cool!
This warmth has been enclosed in the core of our planet since the beginning of time, and can only be difficult to escape because in the air-to-empty space there is nothing that can drain the heat.So it takes a huge long time for the earth to become a stone clog.
It does not help that the nucleus also contains unstable isotopes that fall apart in nuclear reactions, generating more heat.And in addition, the planet receives a lot of warmth in the form of light from our sun, which also keeps things pretty warm.
The Earth’s crust ensures that the core does not emit heat as light, and the atmosphere is also able to hold heat rather than release.
In short, there is a lot of energy in the core that cannot escape.But eventually the planet becomes a solid block of stone and metal. But you and I don’t go along…
It is important to understand what warmth is. Where do you get your heat from (physically)?
We as humans are moving organisms and to be able to move, we must use muscles.Those muscles that have oxygen need for combustion.That is a process that makes sugars usable for the cells in the body.Burning, says it all, ensures conversion of matter to energy… and that’s just what warmth is. Radiation energy. In your body, heat is first created at digestion (where the body breaks down food into smaller parts, namely raw materials that can be absorbed into the blood). This process takes a lot of energy and the processes in the intestines provide movement and warmth.
Why this piece about the human body?Nuwel, heat is energy that is released during a process. It’s not a sale where you can grab it and forward it. We cannot pack heat and send it to the Arctic. We can send raw materials, explain how to make fire in harsh cold conditions and so provide warmth. The core of the earth does not come from heat. It has already received it by impact of meteorites and in addition there are substances (radioactive substances) in the liquid outer core, which emit radiation, which keeps everything warm for a reasonable number of millions of years.
Of Wikipedia (because it is a little better words):

Eh, the core of the Earth is not liquid and does not cause heat.The inner core provides friction with the other layers for friction (which, as you know, excites heat, such as when you rub your hands over each other). All in all, there are several reasons (from movement to radiant heat) why the outer earth core is warm and remains. Nowhere is this contrary to the laws of thermodynamics. Worse. Because we know how the warmth of the earth is caused, we can substantiate the laws and vice versa. With the laws we have been able to determine how the inside of the earth is roughly in the way.
Among others from the decay of certain radio-active elements.The planet Jupiter still seems to shrink and it seems to get the energy it radiates which is more than what it receives from the sun.
