3. Relative dating
Determining the relative order of past events (i.e., the age of an object in comparison to another), without necessarily determining their absolute age
Puts things in sequence order

7. Relative Dating vs Absolute dating
Pg 66

8. Absolute dating
Tells a more accurate date for fossils by using a number age or range
More like calendar dating
Uses observations of the fossil to tell about the past

9. Half Life
The time required for the amount of something to fall to half its initial value.
molecules go through it after a long time giving us the ability to calculate age

10. Carbon dating
-Using the decay of carbon to determine the date of an object
-Carbons half life is years
-Is limited to 75,000 into the past and piece of fossil must be converted to CO2

13. Potassium-argon dating
Can see up to 1.3 billion years into the past
Only reviles the last date it was heated up since argon is a noble gas (doesn’t really bind)
