He is best known, however, for his role in popularising the doctrine of uniformitarianism. According to this theory the earth was shaped entirely by slow-moving forces still in operation today, acting over a very long period of time. In his three volume Principles of Geology (1830-1833), Lyell documented the fact that the earth must be very old and that it has been subject to the same sort of natural processes in the past that operate today in shaping the land. These forces include erosion, earthquakes, glacial movements, volcanoes, and even the decomposition of plants and animals.
