4 How long ago did the solar system form? Radioactive Decay Radioactive decay - atomic nucleus spontaneously loses energy Parent nuclei transforms to daughter nuclei We know the decay rate 4

5 Exponential Decay and Radiometric Dating Each type of radioactive nucleus decays at its own characteristic rate, called its half-life Half life is the time when 1/2 of the original amount of material is left

6 Some Naturally Occurring Radioactive Isotopes and Their Half-Lives Radioactive Isotope (Parent) Radioactive Isotope (daughter) Half-Life (years) Uranium Lead Billion Potassium - 40 Argon Billion Uranium Lead Billion Carbon - 14 Nitrogen

7 Say in the year 2000 a fossil had a 14 C abundance of 1 gram. When will the fossil have a 14 C abundance of 0.5 grams? 14 C has a half life of 5730 years A) the year 7730 B) the year C) the year 3730 B.C. D) the year

8 Radiometric Dating Calculating the absolute age of material by measuring the abundance of a radioactive isotope relative to a stable isotope Example: Radiocarbon dating

9 Cosmic Rays High-energy particles that constantly bombard objects in space Mostly they are hydrogen nuclei (protons), helium nuclei and electrons traveling at close to the speed of light Many produced by Supernovae Interact with particles in Earth s atmosphere, cause a cascade of other particles This interaction produces Carbon-14, 14 C which will decay (is unstable) 9

10 Radiocarbon Dating Assuming Cosmic Ray flux is constant Know how much 14 C is produced Compare with 12 C (stable) In the atmosphere: Ratio ( 14 C/ 12C) atmosphere = constant = 1 part per trillion Measure ( 14 C/ 12 C) sample The ratio of (sample/constant) give age

11 Radiocarbon Dating Ratio ( 14 C/ 12 C) atmosphere = constant (1 part per trillion) If a fossil has a ( 14 C/ 12 C) ratio of 1 part per 4 trillion and 14 C has a half life of 5730 years. How old is the fossil? A)5730 years B)11460 years C)17190 years D)22920 years

12 Radiocarbon Dating at UA Dead Sea Scrolls 200 B.C. to 68 A.D. Shroud of Turin 1300 A.D.

13 Radiometric Dating of Rocks Can tell when a rock solidified: Uranium has a half life of 4.5 billion years Oldest rocks on Earth: Acasta gneiss in Canada s Northwest Territories are 4.03 billion years old (Gyr) Oldest mineral grains on Earth: Zircon grains from Western Australia Gyr Because plate tectonics are active Earth Rocks are not a good indicator for Solar System age

14 Radiometric Dating of Meteorites Oldest rocks in the solar system are meteorites (pieces of asteroids that land on Earth) Radiometric dating of meteorites reveals that they are all nearly the same age Gyr 4.5 Gyr taken to be the age of the Solar System (and Earth)

15 Age of Earth: 4.5Gyr how do we know? radiometric dating of meteorites (formed when solar systems was forming) 15

16 Earth s Internal Structure Temperature and pressure increase with depth Inner core is solid and made mostly of Iron Outer core is molten (liquid) and made of Iron Mantle is solid and made of iron, magnesium and other minerals

17 Earth s Internal Structure Inner Core -solid 80% iron, 20% lighter (Ni,O,S) Pressure keeps it solid Molten outer core -liquid Same composition as inner core Lower mantle - convective Upper mantle - solid but weak Lithosphere Floats on top of upper mantle Region of earthquakes, mountain building, volcanoes, continental drift

18 Surface of Earth - A Jigsaw Puzzle? Alfred Wegener (1915) Observations Continents on either side of Atlantic ocean fit together like pieces of a puzzle Fossils of particular species found in both South America and Africa Glacial sediments in South America, Africa, Asia, India, Theory: Continental Drift - later Plate Tectonics - not accepted until 1960s

19 Plate Tectonics Theory to explain movement of Earth s lithosphere Lithosphere broken into 8 tectonic plates Boundaries of plates are regions of earthquakes, volcanoes, mountain building, seafloor spreading Movement of plates few cm/year Three types of boundaries: -Divergent -Convergent -Transform

20 Plate Boundaries Divergent Boundaries - regions are spreading sea floor spreading Convergent Boundaries - boundaries are colliding subduction zones Transform - slipping

21 Plate Tectonics -Modern Evidence Mid Ocean ridges continents do not just move through the sea sea floor spreads carrying continents with it

22 Plate Tectonics -Modern Evidence Subduction Zones Pacific Ring of Fire- Region of large numbers of Earthquakes and Volcanoes 75% of Worlds active And dormant volcanoes 80% of World s largest earthquakes

23 Plate Tectonics - Modern Evidence Earthquakes at plate boundaries - San Andreas Fault - transform
