Charles Lyell Pins and Buttons
Main Tag:
Description: This scientific diagram shows a key whose bit is made of colorful rock strata, above the motto The Present Is the Key to the Past in classic serif capitals, on a deep dark background. In Principles of Geology (1830), Charles Lyell argued that the processes acting today, erosion, sedimentation and volcanism, explain the history of the Earth. His uniformitarianism deeply influenced Darwin. A gift idea for geology lovers, geography teachers and earth-science students, and a fitting piece for a study or office wall.
