Absolute dating

Difference between relative and absolute dating. What a simple but effective diagram!

The timing of many evolutionary and geologic events on Earth has been determined through two complementary lines of evidence: relative dating and absolute (numerical or radiometric) dating. This evidence makes it clear that life is very old and places a timescale on the pace of evolutionary change, diversification, and extinction. Relative dating places fossils in a

Radiometric Dating: uses unstable isotopes of naturally occurring elements; decay/ change into different elements or isotopes of same; each decays at particular, constant rate, measured in half-life; 1 half-life: amount of time it takes for 50% of parent isotope to decay into daughter isotope; number of decay events observed depends only on how many atoms are present; decay rates not affected by temp, moisture or other factors; natural clock; potassium-argon & uranium-lead used for age of…
