PPT-Notes Geology Chapter 2.3: Geologic Time

Who was James Hutton In the late 1700s James Hutton began to question some of the ideas regarding the Earth He found fossils and saw them as evidence of life forms that no longer exist Different types of fossilized creatures were found in different layers of rock.
