Question 1

Why do geologists use the radiometric age of meteorites as a guide to age of the solar system?

Accepted Answer

A) The meteorites have been isolated in the cold vacuum of space since their formation,so they have seen no significant heating since the time of their formation. 
B) The geologists are guessing because they yield some of the oldest radiometric ages. 
C) The meteorites date the time of formation of a dead planet and don't have anything to do with the age of the solar system. 
D) The meteorites have compositions close to Earth materials,so we assume they formed at the same time.
