The age of Earth was calculated to be about 24-40 million years based on the laws of thermodynamics. Unknown at the time was that the Earth has an internal heat source (radioactive decay) In 1899, John Joly (Irish) calculated the rate of delivery of salt to the ocean.
How do scientists figure out Earthâs age? In the early part of the 20th century, scientists still werenât sure how old Earth is.
