WebWatch on. Secular scientists date the Earth to about 4.5 billion years old by using selected radiometric dating results. Ultimately, what they call “deep time” serves as the very foundation of evolution theory. High school biology books openly acknowledge this necessary connection: Evolution takes a long time. WebMar 23, 2016 · Sedimentary rocks may have radioactive elements in them, but they have been re-worked from other rocks, so essentially, there radiometric clock has not been re-set back to zero. However, sedimentary rocks can be age dated if a volcanic ash horizon or a diabase sill or dyke can be found within the sequence. For example, if you find a …

WebUsing the decay curve shown on this graph, estimate the age of the rock. An example is provided (in blue) for a 40 K proportion of 0.95, which is equivalent to an age of approximately 96 Ma. This is determined by drawing a horizontal line from 0.95 to the decay curve line, and then a vertical line from there to the time axis.
