WebbHere we will look at how plate tectonics has changed the face of the earth over the last few billion years and how it is continuing to change. The idea of continental drift was the forerunner of the theory of plate tectonics. Plate tectonics is thought of as the unifying theory as all of geology can be explained using it.

Webb10 juli 2024 · Charles Lyell was one of the most influential geologists in history. His theory of uniformitarianism was a great influence on Charles Darwin. Lyell theorized that geologic processes that were around at the beginning of time were the same ones that were happening in the present as well and that they worked the same way.

Published in three volumes in 1830–1833 by John Murray, the book established Lyell's credentials as an important geological theorist and popularized the doctrine of uniformitarianism (first suggested by James Hutton in Theory of the Earth published in 1795).
