Geologist uses radiometric dating dating ukranian gilrs sites
Here is an easy-to understand analogy for your students: relative age dating is like saying that your grandfather is older than you.
Absolute age dating is like saying you are 15 years old and your grandfather is 77 years old.
There are two basic approaches: relative age dating, and absolute age dating.By comparing fossils of different primate species, scientists can examine how features changed and how primates evolved through time.Radioactive elements were incorporated into the Earth when the Solar System formed.The universe is full of naturally occurring radioactive elements.Radioactive atoms are inherently unstable; over time, radioactive "parent atoms" decay into stable "daughter atoms." When molten rock cools, forming what are called igneous rocks, radioactive atoms are trapped inside. By measuring the quantity of unstable atoms left in a rock and comparing it to the quantity of stable daughter atoms in the rock, scientists can estimate the amount of time that has passed since that rock formed.
