### How is the age of an object determined by radiometric dating?

The objects approximate age can then be figured out using the known rate of decay of the isotope. Radiocarbon dating is one kind of radiometric dating, used for determining the age of organic remains that are less than 50,000 years old.

### What is meant by radioactive dating?

Also called: radioactive dating n. any method of determining the age of earth materials or objects of organic origin based on measurement of either short-lived radioactive elements or the amount of a long-lived radioactive element plus its decay product.

### What is a radiometric?

Definition of radiometric 1 : relating to, using, or measured by a radiometer 2 : of or relating to the measurement of geologic time by means of the rate of disintegration of radioactive elements

### What is meant by the term “radiocarbon dating?

Radiocarbon dating is one kind of radiometric dating, used for determining the age of organic remains that are less than 50,000 years old. For inorganic matter and for older materials, isotopes of other elements, such as potassium, uranium, and strontium, are used. The American Heritage® Student Science Dictionary, Second Edition.

### How is radioactive dating used to determine age of an object?

How Is Radioactive Dating Used to Determine the Age of an Object? Radioactive dating uses the decay rates of radioactive substances to measure absolute ages of rocks, minerals and carbon-based substances, according to How Stuff Works.

### What is the purpose of radiometric dating Quizlet?

Radiometric dating, or radioactive dating as it is sometimes called, is a method used to date rocks and other objects based on the known decay rate of radioactive isotopes. Different methods of radiometric dating can be used to estimate the age of a variety of natural and even man-made materials.

### How do scientists determine the age of an object?

For biological objects older than 50,000 years, scientists use radioactive dating to determine the age of rocks surrounding where the material was found. By dating rocks, scientists can approximate ages of very old fossils, bones and teeth.

### How is the age of a rock determined?

For biological objects older than 50,000 years, scientists use radioactive dating to determine the age of rocks surrounding where the material was found. By dating rocks, scientists can approximate ages of very old fossils, bones and teeth. Radiocarbon dating was invented in the 1940s by Willard F. Libby.
