Relative Age – the age of an object in relation to another object If undisturbed, oldest on the bottom and youngest on the top Law of Superposition - layers (strata) that are younger will be deposited on top of layers that are older View DE Interactive “Superposition” Warm Up: Think about the word “recrystallization”. What do you think happens during this process? What type of rock does the word allude to? Homework: 1. “ Determining Which is Older” handout color code rocks and identify which is older 2. Answer today’s E.Q. Page 13 Page 14 21

Forces that Disturb Chronologycontinued 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

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)

Bending – from plate movement Intrusion of magma that formed igneous rock Fault – a plate moved and cracked and shifted existing rocl Bending – from plate movement

Determining Absolute Age… Tuesday, September 23, 2014 Wednesday, September 24, 2014 Tuesday, September 23, 2014 Wednesday, September 24, 2014 Absolute Age / Radioactive Dating Determining Absolute Age Essential Questions (leave space to answer): 1. How do rocks provide evidence of earth’s absolute age? 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 Warm Up What is radioactive dating? How is that different from relative dating? Homework: Bring in plain M&M’s or Skittles for a “sweet” lab! Choose an element from the half- life chart and create a graph representing the daughter and parent element over time. Test – October 1 and 2 Page 19 Page 20 31

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

Determining Absolute Age 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

Practice Time!!! Copy this chart Element Y is found in an igneous rock and we are trying to determine the rocks age. We know Y’s half life is approximately 3,000 years and that the rock is currently 6.25% radioactive. How old is the rock? Element Z is found in an igneous rock and we are trying to determine the rocks age. We know Z’s half life is approximately 3,000 years and that the rock is currently 25% radioactive. How old is the rock? Element X is found in an igneous rock and we are trying to determine the rocks age. We know X’s half life is approximately 3,000 years and that the rock is currently 50% radioactive. How old is the rock? Practice Time!!!
