8. Consider how the heavy elements that make up planets like the earth are formed. Which of the following is most likely to be true about the origin of Earth? a. Earth arose around a very ancient star (our sun) that had had plenty of time to synthesize heavy elements. b. EARTH AROSE IN A REGION OF OUR GALAXY WHERE FEW EARLIER STARS FORMED SO THAT THE HYDROGEN FUEL FOR OUR SUN WAS ABUNDANT. c. Earth arose in a region that was very characteristic of other star forming regions so that other planets like Earth are likely to be very common. d. Earth arose in a region that was very unusual in having many earlier star life cycles so that other planets like Earth are likely to be very uncommon.
