Foundations of the earth (components of the integrated earth system) Earth science = primarily observational (experiments are also used) Can be tested against observation or experiment. Hypothesis testing + formation of a theory (discarding/accepting/re-vamping/new observations) Ex. principle of superposition (exception: overturned strata in mountain belts) Ex. the principle of uniformitarianism (james hutton - theory of the earth) - ancient features of the earth are best interpreted in terms of processes that operate at the present day ( the present is key to the past") Hutton"s unconformity - interpreted the contact between the lower rocks and upper rocks as an ancient erosion surface, produced by the processes similar to those operating at the present day - sedimentary rocks and unconformable appearances. Hutton - very strict principle of erosion (but there have been big changes in earth processes ex. long: evolution of the atmosphere and short term changes) Principle of actualism - moderate version of buttons principle.
