The current estimate for the age of Earth of 4.57 Ga comes from ________.
A)radiometric age dating of meteorites
B)radiometric age dating of sedimentary rocks
C)the light from distant galaxies
D)the amount of nuclear fuel in the Sun

Question

Quizplus · Accepted Answer

Radiometric age dating of meteorites provides the most reliable estimate for the age of the Earth because these rocks likely formed around the same time as the rest of the solar system. Sedimentary rocks would not provide an accurate estimate because their formation involves the accumulation of sediment over time, which does not necessarily reflect the age of the Earth. The light from distant galaxies and the amount of nuclear fuel in the Sun are not directly related to determining the age of the Earth.
