The percentages of uranium and lead in a meteorite are 30 and 70%, respectively. What the approximate age of the meteorite?

Interpretation Introduction

Interpretation:

The approximate age of the given meteorite is to be determined.

Concept introduction:

Uranium-lead dating is the method used to determine the ages of the rocks that were formed about one or more million years ago. It is one of the oldest methods of dating rocks.

The age of a meteorite and a fossil can be determined with the help of radiometric dating.

Explanation of Solution

The table that shows the percentage of each element in a fossil is as follows:

Number of half-lives       %Uranium      %Lead             Age of fossil_            0                            100.0                0                      0            1                             50.0                 50                 4.5×109           2                             25
