Information on radioactive decay is used for radiometric dating. It can be used to determine the ages of rocks, fossils, and younger organic materials.
Clearly, the earth has changed, and the dating of materials on the earth show this. In the really old times, the surface of the earth had no plants. Over time, the plants developed on the earth, and then came animals. Dominant forms came and went, and all this is in the record, dated to some extent by techniques that use radioactive decay rates. Even the rocks, untouched by life, have changed, and this also can be dated based on decay rates.

What is the source of heat in the Earth's interior?
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.
What causes heat in center of earth?
Radioactive Decay
Where does heat originate from the earth?
Underground - from radioactive decay.
What is a colorless naturally occurring radioactive inert gaseous element formed by radioactive decay?
It is radon that we see formed from the decay of naturally radioactive substances in the earth's crust.
How has the amount of earth's radioactive isotopes changed over time and why has it changed?
They have been slowly declining over time because they decay, eventually becoming stable isotopes of other elements.

What is the link between the radioactive decay of the earth's core and convection currents?
The radioactive decay produces heat energy, which keeps the convection currents moving.
What alkaline earth metal is radioactive?
There are two radioactive alkaline earth metals: radium (Ra) and radium (Ra). Both elements have radioactive isotopes that undergo radioactive decay.
