"Click on the image to see it more clearly" In an igneous rock layer that had Uranium (parent isotope) and lead ( daughter product ), you analyzed the ratio of the two atoms, you discovered that two half lives have passed, what would be the age of the igneous rock ? ( Note: half life of Uranium is 704 millions years)

• 1408 years

• 1408 million years

• 704 million years

• 500 million yearts
