Unraveling Earth's History: Concepts in Geologic Dating & Chronology

Explore the principles of geologic dating through concepts such as varve bands, half-life decay, carbon dating, tree rings, and radiometric dating methods. Learn about relative and absolute dating techniques, including catastrophism and uniformitarianism. Delve into the contributions of early geologists like Hutton and understand the importance of factors like rate of deposition and erosion in determining the Earth's chronology.

Email to pharman@hoover.k12.al.us Varve Band of silt deposited annually by lakes or glaciers Half life The time it takes for half the atoms of an element to decay Carbon dating Used for organic material less than 70,000 yrs Tree rings Used to determine annual growth of trees Radiometric dating Method to determine to absolute age of an object 5730 yrs Half life of carbon 14 • Reading the rock record • Two main methods • Absolute dating • The numeric age of an event • Relative dates • The age of an object as compared to other objects • Catastrophism • Early idea used to explain geologic processes • Uniformitarianism • The present is key to the past • Hutton • Father of modern geology • Rate of deposition • Dating method used for common sedimentary rocks • Rate of erosion • Example Niagara Falls
