Based on radio-isotopic rock dating techniques, how old is the Earth? Note of caution: watch out between millions and billions.

A. 4.6 million years old
B. 6,000 years old
C. 10,000 years old
D. 4.6 billion years old
E. 46 million years old
F. Scientists really have no clue
G. 46 thousand years old

Answer :

Final answer:

The Earth is approximately 4.6 billion years old, determined by radiometric dating and uranium-238 dating of the oldest known rocks and meteorites.

Explanation:

Using the technique of radiometric dating, scientists have determined that the age of the Earth is approximately 4.6 billion years old. This is based on measurements of the oldest known rocks and estimates from meteorites found on Earth, which are remnants of the solar system's formation. The radioactive dating method, specifically uranium-238 dating, has been instrumental in painting a more accurate picture of our planet's age, greatly refining earlier estimates. The existence of rocks that are about 3.5 × 10⁹ years old marks a significant period post-Earth's surface cooling, allowing for these oldest rocks to solidify. Additionally, using geochronology, the decay of radioactive isotopes within rock formations provides a reliable clock for determining the Earth's antiquity.
