Sir Charles Lyell

Sir Charles Lyell was a prominent 19th-century geologist known for advancing the study of geology and proposing the principle of uniformitarianism. This concept suggests that the Earth's geological processes, such as erosion and sedimentation, have operated consistently over long periods. Lyell's influential work, "Principles of Geology," argued that understanding current natural processes could help explain Earth's history. His ideas laid the groundwork for modern geology and influenced Charles Darwin’s theory of evolution by emphasizing the vast timescales over which geological changes occur. Lyell's contributions helped shift scientific views toward a more dynamic understanding of the Earth’s structure and history.
