What is the definition of absolute dating
Imagine it this way: If you have any siblings, using relative age dating would be like saying, 'I am older than my brother but younger than my sister,' but using absolute age dating would be like saying, 'I am 23 years old.' Since scientists work with many different types of Earth materials (rock, fossils, etc.), there are many types of absolute age dating.
Some types are useful in certain situations and for certain materials, while others are perfect for other jobs.
For example, while one type of absolute age dating may be perfect to figure out how old a dinosaur bone fossil is, another method of dating might be perfect to figure out the age of a rock sample.
Let's look at a few prominent types of absolute age dating.
In the field of archeology, the term "absolute" is somewhat misleading.
Chronometric or calendar dating is a better choice.
Dendrochronology: This is just a fancy term for counting tree rings!
This method is a bit vague, which is why modern scientists have developed many methods by which to determine the absolute age of Earth materials.
You can test out of the first two years of college and save thousands off your degree.
Anyone can earn credit-by-exam regardless of age or education level.
The absolute age of a material is much more desirable when constructing the timeline of our planet because it does not rely on comparisons to other materials.
Instead of saying a material is older or younger than something else, scientists can simply report the age in years.
