A)It gives the general ages of rock strata.(±1 million years).
B)It gives exact ages of rock strata.(± 1 year).
C)It uses a technique in which the degree of radioactive decay is measured,the younger the rock the more radioactive decay.
D)It uses a technique in which the degree of radioactive decay is measured,the older the rock the more radioactive decay.
E)It does not work well with fossil remains that have not absorbed radiation.

Radioactive dating techniques use a technique in which the degree of radioactive decay is measured, and the older the rock, the more radioactive decay there will be. This method provides an accurate estimate of the age of a fossil or rock layer. However, it is important to note that the margin of error increases the further back in time that the materials are being dated.
