So far we’ve looked at early attempts to determine the age of the Earth, let’s now consider how other scientists were trying to work out its history. The term geological history refers to the sequence of historical events from the formation of the Earth to the present day.. POLSAR LAND . COVER CLASSIFICATION . Don Atwood. 1. and David Small. 2.

To . determine the relative age of different rocks, geologists start with the assumption that unless something has happened, in a sequence of sedimentary rock layers, the newer rock layers will be on top of older ones. This is called the Rule of Superposition.. Objectives: . Understand the difference between relative and absolute time.. Summarize principles scientists use to determine the age of rocks.. Relate conservation of matter to radiometric dating.. How do you think scientists tell the age of fossils?. SRJC, Physics 43, Spring 2011. Aaron Krive, Kevin . Chee. History.
