Principles of Geology: being an attempt to explain the former changes of the Earth's surface, by reference to causes now in operation is a book by the Scottish geologist Charles Lyell, first published in 3 volumes in 1830–1833.
Lyell used geology throughout as a basis to strengthen his argument for Uniformitarianism. He used geological proof to determine that the Earth was older than 6,000 years, as had been previously contested. The book shows that the processes that are occurring in the present are the same processes that occurred in the past.
