A) Your team of geologists think the Earth was formed at about the same time as all the other rocky materials in our solar system, including meteorites. The oldest meteorites ever found on Earth contain nearly Equal amounts of both U238 and Pb206. Based on the data (Table 8.1 and graph attached) determine the age of the Earth. EXPLAIN YOUR REASONING. (Hint: Absolute age of meteorite, relative age of Earth).
B) Based on the known hydrogen to helium ratios in the sun, and known rates of nuclear fusion, scientist have calculated the age of the sun at 4.6 billion years. How does this compare to your calculated age of the Earth?
C) Are the two dates consistent?
D) Why would the sun need to exist first?
