It helps keep the Earth's interior hot.
One reason is that radioactive decay heats the earths interior

radioactive decay
Earth's surface is free to radiate heat into space. The interior is not. The interior does transfer heat the the surface, but rather slowly. It is hot due to residual heat from Earth's formation and from the heat generated by the decay of radioactive elements.
Decay of radioactive elements in the mantle heats it.
The main sources of heat in the Earth's interior are residual heat from the planet's formation, radioactive decay of elements like uranium, thorium, and potassium, and heat generated by ongoing processes like mantle convection and core formation. This heat leads to processes like plate tectonics, volcanic activity, and the Earth's magnetic field.
light and heat(i heard some1 say radiation 1ce but i dont think its true)
The aesthenosphere is kept deformable largely through heat generated by radioactive decay
Pressure does not have a significant effect on the rate of radioactive decay, as it is mainly influenced by the instability of the nucleus of the atom. The decay process is determined by the nuclear forces within the atom, which are not significantly affected by external pressure changes.
Radioactive decay
Yes. That is what causes some of the Earths core heat. Elements being formed by radioactive decay. Look at the Earths' makeup and see that the percentages of elements follows the periodic chart by decay.
As elements decay within the Earth's interior, they release energy. This energy creates movement within the magma (along with the rotation of the Earth and heat) and this movement causes the plates of the Earth to move, hence the geography of the planet is different to thousands and millions of years ago.
