3. You should already know this. It’s common sense. You just NEED to know…

6. THE LAW OF SUPERPOSITION:

7. THE LAW OF SUPERPOSITION:
The more you dig BELOW…

8. THE LAW OF SUPERPOSITION:
The MORE you dig BELOW…

9. THE LAW OF SUPERPOSITION:
The MORE you dig BELOW…
…the OLDER you go!

10. THE LAW OF SUPERPOSITION:
The more you dig BELOW…
…the OLDER you go!
160 million year old rodent fossil

11. you think this is big…

12. We dug further down back in time & discovered even BIGGER rodents
We’d have to build stronger refrigerators.

13. THE LAW OF SUPERPOSITION:
The MORE you dig BELOW…
…the OLDER you go!
What are these fossils?

17. THE MORE YOU DIG BELOW…THE OLDER YOU GO!
Remember!!!!!!
THE LAW OF SUPERPOSITION is…
THE MORE YOU DIG BELOW…THE OLDER YOU GO!

18. newer layers LAY ON TOP OF older layers.

19. LAW of SUPERPOSITION = RELATIVE DATING.

20. LAW of SUPERPOSITION = RELATIVE DATING
What’s “relative” mean here?

21. LAW of SUPERPOSITION = RELATIVE DATING
Nooooo,

22. geologists, archaeologists, & paleontologists use this law of superposition to relatively date & tell our earth’s history.

23. WHAT DOES IT MEAN TO “RELATIVELY DATE”?
DATE is a VARIABLE that is a measure of _ _ _ _.

24. WHAT DOES IT MEAN TO “RELATIVELY DATE”?
DATE is a VARIABLE that is a measure of TIME.

25. WHAT ELSE CAN WE “RELATIVELY” measure?
Would you say…

26. play game: relative weighing, dating, measurements of properties of all kind.

27. WHAT ELSE CAN WE “RELATIVELY” measure?
WHEN WE DO A “RELATIVE” comparison is it exact and precise?

28. RELATIVE DATING is just a logical comparison between layers
RELATIVE DATING is just a logical comparison between layers. how layers relate to each other or as they relate to another event.
IT’S A LOGICAL COMPARISON (no numbers needed)!

29. RELATIVE like…
Who is relatively colder?

30. RELATIVE like…
Who is relatively colder?

31. DO WE KNOW EXACTLY HOW MUCH COLDER?
RELATIVE like…
Who is relatively colder?
DO WE KNOW EXACTLY HOW MUCH COLDER?

32. DO WE KNOW EXACTLY HOW MUCH COLDER? NO.
RELATIVE like…
Who is relatively colder?
DO WE KNOW EXACTLY HOW MUCH COLDER? NO.

33. RELATIVE like… Who is RELATIVELY younger?
DO WE KNOW THE EXACT AGE OF THESE KIDS?

34. RELATIVE like… Who is RELATIVELY younger? NO
DO WE KNOW THE EXACT AGE OF THESE KIDS?

35. RELATIVE like… Which is relatively fresher?
DO WE KNOW THE EXACT DAY THESE FRUITS WERE PICKED?

36. RELATIVE like… Which is relatively fresher? NO
DO WE KNOW THE EXACT DAY THESE FRUITS WERE PICKED?

37. DO WE KNOW THE EXACT LENGTH
RELATIVE like…
Which nose is relatively longer?
Which is LONGER?
DO WE KNOW THE EXACT LENGTH
OF EACH NOSE?

38. DO WE KNOW THE EXACT LENGTH
RELATIVE like…
Which nose is relatively longer?
Which is LONGER?
DO WE KNOW THE EXACT LENGTH
OF EACH NOSE? NO

39. RELATIVE DATING is just a logical comparison between layers
RELATIVE DATING is just a logical comparison between layers. how layers relate to each other or as they relate to another event.
IT’S A LOGICAL COMPARISON (no specific numbers)!

40. RELATIVE DATING is just a logical comparison between layers
RELATIVE DATING is just a logical comparison between layers. how layers relate to each other or as they relate to another event.
IT’S A LOGICAL COMPARISON (NO SPECIFIC DATES)!

41. RELATIVE like…
Which one is RELATIVELY younger?

42. RELATIVE like…
Who is RELATIVELY faster?

43. Which plane is RELATIVELY closer?
Do we know exactly how far away each plane is?

44. LAW of SUPERPOSITION = RELATIVE DATING = NOT EXACT
