Document Summary
Geology: a science that deals with the history of the earth and its life especially as recorded in rocks. Physical geology: involved with the processes that act to form the earth and the products of those processes (eg: minerals, plate tectonics, earthquakes) Historical geology: involved with the interpretation of the history of the earth. Environmental interpretation of rocks + age of rocks = earth history. Environmental interpretation: the present is key to the past; examining the characteristics of various environments on earth can interpret the environments in which ancient sediments were deposited. Age of rocks: based on relative age (relative to associated rocks) or absolute age (radiometric dating) Science: is a system of knowledge that is based on general truths or facts as they are known at the time. Science is thus a methodological approach to studying the natural world. Deductive reasoning: to draw conclusions regarding a phenomenon based on all that is known about it.
