4 Earth’s Story How do mountains form? How is new rock formed? 250 years ago these questions were being asked and researched.
5 James Hutton Theory of the Earth The key to understanding Earth’s history is all around us…Uniformitarianism-the same geologic processes shaping the Earth today have been at work throughout Earth’s history
6 Uniformitarianism vs. Catastrophism Geologic processes take millions of years.Catastrophism-principle that states that all geologic change occurs suddenly.Catastrophes?
7 Charles Lyell Principles of Geology (1830-1833) Challenged the principles of catastrophismGeologic change happens gradually.
8 Modern Geology Geology through a happy medium Evidence through craters and recreations
9 Paleontology The study of past life Use of fossils as data collection Invertebrate PaleontologistPaleobotanist
10 Letter to a ScientistWrite a letter to Charles Lyell, James Hutton or Stephen GouldBriefly explain the position of each scientist in reference to GeologyYou should explain why you agree or disagree with the scientist’s theories.See pagesConclude your letter with at least two questions.
11 Your Goal Working with a partner; Design a poster announcing a debate betweenCatastrophistUniformitarianUse phrases and picturesSummarize the major points of both sides
