And this would also include things like trees and plants, which give us paper and cloth.

So, radiocarbon dating is also useful for determining the age of relics, such the Dead Sea Scrolls and the Shroud of Turin.

With rubidium-strontium dating, we see that rubidium-87 decays into strontium-87 with a half-life of 50 billion years.

By anyone's standards, 50 billion years is a long time.

However, rocks and other objects in nature do not give off such obvious clues about how long they have been around.

So, we rely on radiometric dating to calculate their ages.

Because plants use carbon dioxide for photosynthesis, this isotope ends up inside the plant, and because animals eat plants, they get some as well.

When a plant or an animal dies, it stops taking in carbon-14.

When the isotope is halfway to that point, it has reached its half-life.

There are different methods of radiometric dating that will vary due to the type of material that is being dated.

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.

For example, uranium-lead dating can be used to find the age of a uranium-containing mineral.
