The total energy stored in the earth's magnetic field has steadily increased by a factor of 2.7 over the past 1000 years. 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. This theory matches paleomagnetic, historic, and present data. At that rate the field could not be more than 10,000 years old.
Many strata are too tightly bent.
In many mountainous areas, strata thousands of feet thick are bent and folded into hairpin shapes. The conventional geologic time scale says these formations were deeply buried and solidified for hundreds of millions of years before they were bent. Yet the folding occurred without cracking, with radii so small that the entire formation had to be still wet and unsolidified when the bending occurred. This implies that the folding occurred less than thousands of years after depositional 7. It is very unlikely that the sandstone would not solidify during the supposed 430 million years it was underground.
