which of these ways describes how scientists have tried to calculate the age of earth? select one: a. calculate the rate of evolution and determine how long it would take for modern animals to evolve. b. calculate how long it would take for the earth to cool to its current temperature from a molten ball. c. measure how much sediment a stream deposited in a year and calculate how long it would take to deposit a sediment layer. d. all of these

which of these ways describes how scientists have tried to calculate the age of earth? select one: a. calculate the rate of evolution and determine how long it would take for modern animals to evolve. b. calculate how long it would take for the earth to cool to its current temperature from a molten ball. c. measure how much sediment a stream deposited in a year and calculate how long it would take to deposit a sediment layer. d. all of these

Answer

Brief Explanations:

  • Option a: Evolution - based methods can give insights into the long - term history of life on Earth which is related to Earth's age.
  • Option b: Cooling models of the Earth from a molten state help estimate the time elapsed since Earth's formation.
  • Option c: Sedimentation rate studies can be used to estimate the age of geological layers and thus contribute to understanding Earth's age. Since all these methods have been used by scientists to estimate Earth's age.

Answer:

D. All of these
