7.2 Half Life

7.2 Half Life. A half life can be used to compare the rate of radioactive decay for an isotope. The shorter the half-life, the faster the decay rate. All radioactive decay rates follow a similar pattern called a decay curve.

Geologic Time

Geologic Time By examining layers of sedimentary rock, geologists developed a time scale for dividing up earth history. Earlier in the 20 th century, radiometric-dating techniques allowed scientists to put absolute dates on divisions in the geologic time scale.
