Describe how carbon 14 is used as a dating method
This method is based on the assumption (which nearly always holds true) that deeper layers of rock were deposited earlier in Earth's history, and thus are older than more shallow layers.
The successive layers of rock represent successive intervals of time.
By measuring the amount of original and transformed atoms in an object, scientists can determine the age of that object.
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.Relative dating methods are used to determine only if one sample is older or younger than another.Absolute dating methods are used to determine an actual date in years for the age of an object.When carbon-14 falls to Earth, it is absorbed by plants.These plants are eaten by animals who, in turn, are eaten by even larger animals.
