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 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.

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?

The absolute age of an igneous rock can best be determined by radiometric dating methods, such as uranium-lead dating or potassium-argon dating. These methods rely on the natural decay of radioactive isotopes in the rock to calculate the time elapsed since the rock formed.

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 is absolute age?

Absolute age refers to the exact age of a rock, fossil, or other geologic feature in years. It is typically determined using radiometric dating techniques that measure the decay of radioactive isotopes within the object. This method provides a more precise and accurate age compared to relative dating methods.

How can the absolute age of a rock be determined?

The absolute age of a rock can be determined through radiometric dating methods, such as carbon dating or uranium-lead dating. These methods rely on the known rates of decay of radioactive isotopes within the rock to calculate how long it has been since the rock formed. By measuring the ratios of parent and daughter isotopes, scientists can determine the rock's absolute age.

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.

The age in years of a rock or other object is a what?

The age in years of a rock or other object is a representation of the time that has passed since its formation. This age can be determined through various methods such as radiometric dating or relative dating techniques.

How might relative and absolute age be used to establish ages in a series of rock layers?

Relative age is determined by the position of rock layers in relation to one another, using principles like superposition and cross-cutting relationships. Absolute age is determined by radiometric dating of the rocks themselves, providing a more precise numerical age of when the rocks formed. By combining these methods, scientists can establish a timeline of events in a series of rock layers.

What is relative and absolute age?

Relative age refers to the age of an object or event in relation to other objects or events, typically determined through stratigraphy and the law of superposition. Absolute age refers to the specific number of years since an object or event formed, usually determined through radiometric dating techniques.
