40. SCIENTISTS USE RADIOMETRIC DATING TO DETERMINE THIS KIND OF AGE OF ROCK.

41. WHAT IS ABSOLUTE AGE?

42. SEDIMENTARY ROCK LAYERS OLDER THAN THE LAYERS ABOVE IT AND YOUNGER THAN THE LAYERS BELOW IT IS DUE TO THIS LAW.

44. SEDIMENTS DEPOSITED IN LAYERS FORM THIS KIND OF ROCK.

45. WHAT IS SEDIMENTARY?

46. SOMETIMES ROCK LAYERS GET OVERTURNED OR FOLDED DUE TO THESE STRONG EARTH FORCES.
