Question: What is the radiometric age of the Earth?

All the data from Earth and beyond has led to the estimated age of 4.5 billion years for our planet. The age of rocks is determined by radiometric dating, which looks at the proportion of two different isotopes in a sample.

What is the suggested age of Earth?

4.54 billion years old Earth is estimated to be 4.54 billion years old, plus or minus about 50 million years. Scientists have scoured the Earth searching for the oldest rocks to radiometrically date. In northwestern Canada, they discovered rocks about 4.03 billion years old.

How old is the Earth according to paleontologist?

4.54 billion years old Scientists now know the Earth is actually 4.54 billion years old, an age built on many lines of evidence from the geologic record.

How is Earth age determined?

The best estimate for Earths age is based on radiometric dating of fragments from the Canyon Diablo iron meteorite. From the fragments, scientists calculated the relative abundances of elements that formed as radioactive uranium decayed over billions of years.
