That is, scientists cannot tell exactly how old the layers are in years to the present date, only which is older than the other.
the whole fossil is converted to carbon, occurs when an organism is buried under fine sediment.
as time passes, pressure squeezes out the liquid and gaseous components and leaves behind a thin residue of carbon.
if the carbon film is lost, an impression may remain.
Know More Relative age comes up often in various fields, such as archeology.
If archaeologists find a site with layers in it, they can make assumptions about the relative age based on the composition of materials in each layer.
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.Collins English Dictionary - Complete & Unabridged 2012 Digital Edition © William Collins Sons & Co. 1979, 1986 © Harper Collins Publishers 1998, 2000, 2003, 2005, 2006, 2007, 2009, 2012 Cite This Source "to set free, make separate" (see absolve).Most of the current senses also were in the Latin word.Relative age allows scientists to know whether something is older or younger than something else, while absolute age means that scientists know the exact number in years that have passed since the object was created.Relative age will require the comparison of two or more objects, whereas absolute age does not.
