In this module we compared the evolution and creation timelines. We saw that when the timelines are compared, the order of the events is very different. We investigated continental drift and plate tectonics in Continental Drift, Plate Tectonics, And The Bible.
We examined:
The underlying assumptions for radiometric dating  | | Assumption 1: | Constant decay rate through history | | Assumption 2: | The system is closed to the environment (nothing has happened in the process to add to or to take away from the amount of each isotope) | | Assumption 3: | Known concentrations at the start | | Assumption 4: | The earth is old | | Assumption 5: | Creation is not a possible option | |
The problems with those assumptions | | 1. The process is not totally isolated from the environment | | a) Uranium can be converted by water percolation
b) Leaching and biological activities can add and remove isotopes
| 2. Assumed concentrations have been demonstrated to be wrong—Some igneous rocks from recent volcanoes have both radioisotope samples and give wrong age
| And other problems with radiometric dating | | 1. In the Grand Canyon, igneous rocks from top layer (volcano reported by Indians) dated older than igneous rocks from the bottom
2. Different dating procedures (U/Pb vs. Rb/Sr) result in drastically different ages
