Term

Simultaneous Accretion

 

Hypothesis for the Origin of the Moon

Definition

  • 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

Term

Fission

(bud off of Earth)

 

Hypothesis for the Origin of the Moon

Definition

Hypothesis for the Origin of the Moon

Definition

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

Term

Impact

 

Hypothesis for the Origin of the Moon

Definition

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

Term
Hubble Law
Definition

  • 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

Term

Background radiation

Microwave radiation

Background Noise

Definition

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

Term
Heat Sources for the Early Earth
Definition

  • Carbonaceous Chondrites
  • Photolysis

Term
Carbonaceous Chondrites
Definition

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

Term
Volcanic Degassing
Definition
Possible source of water for oceans
Term
Photolysis
Definition

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

Term
