# '''Geomagnetic field decay'''

#:"Observations made of the strength of Earth's magnetic field over the last 150 years show that it is decaying, which puts an upper limit on the age of the Earth.

Evolutionary theories explaining this rapid decrease, as well as how the earth could have maintained its magnetic field for ''billions of years'' are very complex and inadequate. A much better creationist theory exists. It is straightforward, based on sound physics, and explains many features of the field: its creation, rapid reversals during the Genesis flood, surface intensity decreases and increases until the time of Christ, and a steady decay since then. This theory matches paleomagnetic, historic, and present data, most startlingly with evidence for rapid changes. The main result is that the field's total energy (not surface intensity) has always decayed at least as fast as now. At that rate the field could not be more than '''20,000 years''' old."<ref name="icrye" />

#:"Radioactive inclusions in rock often cause concentric spheres of discoloration due to the damage caused by alpha particles as they are emitted by the radioactive substance. Pleochroic halos are the scars of radioactive decay, particularly alpha decay. These scars appear as spheres (rings when views in cross-section) in the rock surrounding a decaying radioactive atom. The size of the halo is a signature of the energy of the emission and therefore the element and isotope involved. Creationists use these halos in several ways to suggest problems with the standard uniformitarian model."<ref name="cwye" />

#:"The main assumption of radiometric dating is that the decay rates are constant with time. If the decay rate has varied significantly over time then any date based on radioactive decay is worthless. However, if radioactive decay has been happening for Billions of years then there is insufficient argon diffusion, insufficient lead diffusion, insufficient helium in the air, and too much Helium in Rocks. Recent experiments commissioned by the RATE group indicate that "1.5 billion years" worth of nuclear decay has taken place, but in one or more short periods 4000 – 8000 years ago. This would shrink the alleged 4.5 billion year [[radioisotope]] age of the earth to only a few thousand years."<ref name="cwye" />

According to secular scientific literature, that process presently removes only 1 billion tons per year. As far as anyone knows, the other 19 billion tons per year simply accumulate. At that rate, erosion would deposit the present mass of sediment in less than '''12 million years'''. Yet according to evolutionary theory, erosion and plate subduction have been going on as long as the oceans have existed, an alleged ''three billion years''.
