Question

which information provides evidence that has helped earth scientists determine the age of the earth more precisely?
radioactive dating
carbon dioxide formation
index fossils
earths distance from the moon

Explanation:

Radioactive dating uses the known half-lives of radioactive isotopes to measure the age of rocks and minerals with high precision, allowing scientists to calculate the Earth's age accurately. Index fossils only provide relative age estimates, carbon dioxide formation and Earth-moon distance do not relate to precise age determination.

Answer:

radioactive dating
