B2

The condensation hypothesis for the formation of the moon suggests that the moon and Earth formed as a double planet from the same cloud within the solar nebula. It predicts   a. that the moon and Earth should have nearly the same mass and radius.   b. that the surfaces of the moon and Earth should be very similar and show evidence of plate tectonics.   c. that the moon and Earth should have identical compositions and densities.   d. all of the above.   e. a and c.

14. Based on what the nebular theory tells us about the formation of our own solar system, what does the theory predict for the possibility of other planetary systems? Group of answer choices Other planetary systems should be identical to our own. Planetary systems should be very rare. Most stars should have one or two planets, but not more. Planetary systems should be common.   15. Which of the following statements best describes the accomplishments of these three people?
