The absolute age of a rock is the approximate number of years ago that the rock formed The absolute age of an igneous rock can best be determined by?
It is best determined by radiometric dating techniques which measure the decay of radioactive elements.
What is the purpose of absolute dating?
Absolute geologic age is determined through radiometric dating, and is the most precise method for determining the age of a rock or fossil within a small range. Relative geologic age is determined by the index fossils that may be contained within the rock that indicate a much broader range of possible ages based on the time the organism existed on Earth.
The half-life of an element is used in determining what characteristic of a particular rock?
The absolute age of a rock is determined by the amount of decay of certain elements as interpreted from their known half-life. The absolute age is stated in a number of years with a margin of error, as opposed to the relative age, which is more of a range of years in which the rock could have formed, based on index fossil evidence and the law of superposition.
The age in years of a rock or other object is a what?
The age in years of a rock or other object is known as Absolute Age.
The number of years since a rock has formed?
absolute age
What is absolute age?
Absolute age is the age of a rock as determined by the measurement of radioactive decay from the time of the rock's formation.

It is best determined by radiometric dating techniques which measure the decay of radioactive elements.
How can the absolute age of rock be determined?
Through Radioactive Dating or Isotopic Dating.
What is the true age of a rock or fossil?
The method used will be determined by the rock type, but the age of a rock will be determined by a determination of the amount of decay of a radioactive isotope, either contained in the rock, or in a geologic layer of rock coinciding with a fossil.
How can you determine the absolute age of an igneous rock?
Relative age can be determined using superposition and cross-cutting relationships. Absolute age can only be determined using radiometric dating methods, such as Rb-Sr.
How can absolute age based on rates of erosion and deposition be inaccurate?
The absolute age of rock is determined by the amount of radioactive decay, not by the rate of erosion and deposition.
What method do geologists use to determined the absolute age of a rock?
Radioactive dating is used to determine the absolute ages of rocks. By Jennifer Palos
What is the difference between the relative age and absolute age of rocks?
Relative age is the age of a rock relative to the rock layers around it, absolute age is a rock's exact age.
What is the purpose of absolute dating?
Absolute geologic age is determined through radiometric dating, and is the most precise method for determining the age of a rock or fossil within a small range. Relative geologic age is determined by the index fossils that may be contained within the rock that indicate a much broader range of possible ages based on the time the organism existed on Earth.

What is a kind of age of rock that is given in years?
