Question

How to measure the age of the Earth?

• A. Radiometric dating
• B. Carbon dating
• C. Fossil analysis
• D. Geological surveys

Hint:

Radiometric dating is one of the most reliable methods for dating ancient rocks and fossils, based on the decay of radioactive elements.

Answer 1

The Correct Option is A

The age of the Earth is most commonly measured using radiometric dating, which involves analyzing isotopes in rocks and minerals, particularly those in zircon crystals. By measuring the decay of radioactive isotopes like uranium to lead, scientists can estimate the age of the Earth. This method provides a very accurate determination of the Earth’s age, which is currently believed to be around 4.54 billion years.
