Learn about different types of radiometric dating, such as carbon dating.
The main relative dating method is stratigraphy (pronounced stra-TI-gra-fee), which is the study of layers of rocks or the objects embedded within those layers.
The process of putting things in a "correct order" based on experience is called relative dating.
Relative dating is determining whether an object is older or younger than other objects or events.
For example, if an area used for trash has modern refuse in it such as CDs and computers, and the layer underneath has cans made of tin, then it is safe to say the layer of tin cans have a greater relative age than the layer with modern refuse.
However, this does not say anything about the absolute age of the layers.
