Simultaneous Accretion

Hypothesis for the Origin of the Moon

• Composition not necessarily similar to Earth, hypothesis says Moon formed separately from the Earth.
• Says moon is NOT in the plane of ecliptic
• The Moon probably cannot overcome Earth's gravitational attraction

Hypothesis for the Origin of the Moon

Capture

Hypothesis for the Origin of the Moon

• Composition not necessarily similar to Earth
• Moon IS in the plane of the ecliptic
• Moon cannot overcome Earth's Gravitational Attraction

Impact

Hypothesis for the Origin of the Moon

• Likely similar composition to Earth
• Moon perhaps not in the plane of the ecliptic
• Moon can overcome Earth's gravitational attraction

• The more intense and stronger the red wavelengths of an object are, the further away the body is.
• Hubble used this to indicate evidenc that that the universe is expanding

Background radiation

Microwave radiation

Background Noise

• Radiation left over from an early stage in the development of the universe
• Major evidence for the Big Bang theory

• Carbonaceous Chondrites
• Photolysis

• Organic matter (meterorite) that contains ice.
• Oceans may have been formed by these

• Ultraviolet light splitting through Earth's atmosphere 
• Zaps water
• Produces a lot of hydrogen and oxygen
  • Oxygen combines with ammonia, methane, and oxidizes them.
