What is the Giant Impact Hypothesis?
A large body called Theia smashed into the Earth, producing the Earth and the Moon.
What evidence supports the Giant Impact Hypothesis?
- KREEP, oxygen isotopes
- no Moon water
- small iron core
What is the Capture Theory?
The Moon was happily sailing through space when it was captured by Earth’s gravity and began orbiting it.
What evidence helps to disprove the Capture Theory?
- KREEP
- How did the Moon slow down so significantly?
What is the Co-accretion Theory?
The Earth and Moon were formed in the same place.
What evidence suggests that the Co-accretion theory might not be true?
- Why does the Moon have a small iron core?
- Why the inclined and elliptical orbit?
What are the percentages of the cores from the total internal divisions?
Moon - 20%
Earth - 50%
