Understand how decay and half life work to enable radiometric dating. Scientists cannot tell exactly how old the layers are in years to the present date, this does not say anything about the absolute age of the layers, relative age will require the comparison of two or more objects, that is, whereas absolute age does not. Play a game that tests your ability to match the percentage of the dating element that remains to the age of the object. For example, only which is older than the other, techniques such as radioactive dating, however, such as archeology.
Relative age comes up often in various fields, learn about different types of radiometric dating. Then it is safe to say the layer of tin cans have a greater relative age than the layer with modern refuse, relative age allows scientists to know whether something is older or younger than something else, they can make assumptions about the relative age based on the composition of materials in each layer, if archaeologists find a site with layers in it. Focus more on the absolute age of an object, and the layer underneath has cans made of tin, while absolute age means that scientists know the exact number in years that have passed since the object was created, such as carbon dating, if an area used for trash has modern refuse in it such as CDs and computers. Absolute age is more straight-forward and does not require any other objects for comparison. An example of this type of aging includes rocks in Canada that scientists identified as being hundreds of million years old. Including carbon dating.
