Relative and absolute age dating Free 40 plus chat lines cleveland
Instead of saying a material is older or younger than something else, scientists can simply report the age in years.
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.
It is essentially a big sequence: This comes first, that comes next, this comes last.
In order to use this type of dating, the material must be heated to 500 degrees Celsius and the resulting light is measured and analyzed.
Dendrochronology: This is just a fancy term for counting tree rings!
