22. Forces that Disturb Chronology continued Movement of Tectonic plates Can bend layers like a taco (oldest layer may be bent until its on the top. Faults – a break in earth’s crust where rock slips past another Intrusion – magma (igneous rock forms) that has forced its way through existing rock layers

23. Sometimes Rock History Erodes Away Unconformity - a buried erosion surface separating two rock masses or strata of different ages (a missing rock layer due to erosion) erosionrockstrata

Page 19 Homework: 1.Bring in plain M&M’s or Skittles for a “sweet” lab! 2.Choose an element from the half- life chart and create a graph representing the daughter and parent element over time. 3.Test – October 1 and 2 Tuesday, September 23, 2014 Wednesday, September 24, 2014 Page 20 Tuesday, September 23, 2014 Wednesday, September 24, 2014 Essential Questions (leave space to answer ) : 1. How do rocks provide evidence of earth’s absolute age? Determining Absolute AgeAbsolute Age / Radioactive Dating Absolute Age –assigns a quantitative estimate of the number of years ago an event occurred. Determining Absolute Age… Radioactive Dating – using radioactive particles found in a rock to determine the actual age of the rock Radioactivity – Radioactivity is a process in which subatomic particles escape from the nuclei of unstable atoms releasing energy. See diagram atom

32. Which rocks do geologist use? -Igneous rocks are most useful due to unique chemical makeup. Radioactive materials are unchanged. -Sedimentary rock is not as reliable because it’s made of many different rock particles -Metamorphic dating usually results in the age of the change, not the original rock

34. Determining Absolute Age o Use an element’s Half-life: The time it takes for an element to decay. Examples: Carbon-14 has a half-life of 5,730 years. Always found in LIVING organisms Potassium-40 has a half-life of 1.3 billion years Half Life You Tube Using a specific calculation can help you determine the absolute age using half-lives
