Lab 8 dating of rocks fossils and geologic events answers
The theory that the outer layer of the Earth (the lithosphere) is broken in several plates, and these plates move relative to one another, causing the major topographic features of Earth (e.g.
Many geological samples contain multiple parent/daughter pairs, so cross-checking the clocks confirms that radioisotopic dating is highly reliable.

This can be further calculated for a series of half-lives as shown in the table.
The table does not show more than 10 half-lives because after about 10 half-lives, the amount of remaining parent is so small it becomes too difficult to accurately measure via chemical analysis.
Many of the largest mountain ranges and broadest zones of seismic activity come from collisions..
