Let's look at some numerical support for the geological time scale.
In the oceans, particularly in the Pacific, there are chains of sea mounts and islands. The radiometric dates for these chains increase virtually linearly as you go from one end to the other.
The best known one is the Hawaiian -Emperor sea mount chain extending northwest from Hawaii. At least 40 have been dated ranging up to 81 million years, with of course at the Hawaiian end you have the current volcanoes, and a new one under sea S-E of Hawaii.
The volume of the volcanic products in the chain is 750,000 cubic km.The R-M dates are what you would expect for the current rate of movement of the Pacific plate over the hawaiian hot spot.
These chains present at least two problems for YEC.
1. Why do these dates look exactly as you would expect given current nuclear physics and the observed rate of plate movement?
2. How could the chain be formed around the time of the Flood with the extreme rate of plate movement and of volcanism required? The H-E chain alone represents at least 30,000 Krakatoas.
