Thank you! Be sure to use the facts below to complete your chart for this assignment. You should have 3 facts about Relative Dating, 3 facts about Absolute Dating, and 2 facts that are the same for both. All of this information can be found in our lesson! ! 1. The Law of Superposition – the age of an object may be determined by the depth at which it is found, the deeper the object is in the Earth, the older it is. 2. Gives scientist an exact age of a rock or fossil. 3. Scientist use their knowledge of the half-life of carbon and uranium isotopes to measure the age of the rock or fossil. 4. Used to determine the age of an object, when there is no record of a living thing. 5. Gives the approximate age of a fossil or artifact. 6. Used by scientist to determine the age of a fossil or artifact. 7. Estimates the order of geological or prehistoric events, but cannot be used to determine when these events have occurred. 8. Measures the decay of a rock or fossil to measure the age. Check out this amazing video from one of our FLVS teachers, about Relative and Absolute dating! http://www.youtube.com/watch?v=jM7vZ-9bBc0 Check out these awesome websites, to help you find out more information about deforestation, urbanization, and desertification!
