Solution
The correct option is B radio uranium dating
The age of earth can be estimated by radio uranium dating.
In the 1920s, Earth's age crept up toward 3 billion years, making it for
a time even older than the universe, which was then estimated to be about 1.8
billion years old. The best estimate for Earth's age is based on radiometric
dating of fragments from the Canyon Diablo iron meteorite.
All rocks and minerals contain long-lived radioactive elements that were
incorporated into Earth when the Solar System formed. These radioactive
elements constitute independent clocks that allow geologists to determine the
age of the rocks in which they occur.
