How old is the earth?
Answers (1)
Based on evidence from radiometric dating of meteorite material, it is estimated that the age of the Earth is about 4.5 billion years old.
In 1862, the calculation of Glasgow physicist William Thomson suggested that the age of Earth was between 20 million and 400 million years. However, the geologists and biologists thought that was too short. The invention of radiometric dating made the calculation of the Earth's age more accurate.
