Answer

Brief Explanations:

  • Red - shifting and blue - shifting are mainly related to the motion of celestial objects and not directly to determining the age of the Earth.
  • The age of rocks on Earth can give us information about the age of the Earth's crust and through radiometric dating techniques, contribute to age estimates.
  • Cosmic background radiation is related to the early universe and not directly to Earth - age determination.
  • The composition of the universe (amount of hydrogen and helium) is more related to the Big Bang and the evolution of the universe rather than Earth's age.
  • The age of rocks in space, such as meteorites, can be used as they are thought to have formed around the same time as the Earth and can be dated radiometrically.
  • Hubble's Law is about the expansion of the universe and not related to Earth's age.
  • The fact that all objects in the solar system orbit in the same direction is related to the formation of the solar system but not a direct indicator of Earth's age.

Answer:

  • Age of rocks on Earth
  • Age of rocks in space
