Does nuclear fusion go on at the earth's core?

I don't think it does.....but a second opinion doesn't hurt!

    The answer is no.

    Two reasons:

    1. It is not hot enough

    2. The elemental components are not right.

    Fusion is the combination of lighter elements to produce a heavier element. In doing so it releases energy. This is how stars work. As the atomic number increases the amount of energy released becomes smaller, until you get to iron. After this point you have to add energy to fuse to elements together. The core of the Earth is made up of heavy elements that will not fuse. However some of these elements are unstable and will undergo fission; atomic number becomes smaller. It is the decay of these elements that keeps the interior of the Earth warm.

    I agree with KBW3. The light you see from the sun does not come from the core. It comes from the outer layers of the sun which are glowing from the energy produced by the core. If the fusion in the core suddenly stopped, the outer layers would continue to glow for a long time (if you ignore the fact that the sun will collapse and then explode). The same thing happens in a lightbulb. When you turn off a light, the electricity stops flowing immediately, but the bulb continues to glow for a short time because the filament is still hot.

    Fusion is when two or more atom nucleus collide and become a larger nucleu. If the colliding nucleus and the formed nucleus are lighter than iron, the fusion produces heat.

    Fusion need extreme high pressure and temperature cue to the repulsion of the nucleus.

    Fission is when a nucleus is break (by self instability, or by a collision with small particles like neutron). Fission produces heat when the breaking nucleus are heavier than the iron's one.

    Most of elements in the Earth core are heavier than iron. Many have instability (radioactivity).

    The Earth's core low pressure, low temperature and low contend of light elements don't permit the nuclear fusion.

    Similar but not the same.

    Here on earth different types of fusion reactions are involved. The most suitable reaction occurs between the nuclei of the two heavy forms of Hydrogen, these are known as isotopes - Deuterium (D) and Tritium (T); eventually reactions involving just Deuterium or Deuterium and Helium (3He) may be used to do the same thing as Tritium and Deuterium.

    No, but there is much nuclear fission happening there.

    no, not hot enough there for fusion.

    You are right; it doesn't. Not nearly enough heat and pressure.

    No.
