I have a question about Geology and Stratigraphy. Who was the first person to propose the theory of the rock cycle?

The first person to propose the theory of the rock cycle was Charles Lyell. Lyell was a British geologist who lived from 1797 to 1875. He was a proponent of uniformitarianism, which is the idea that the present is the key to understanding the past. Lyell proposed that the Earth was formed by a process of gradual change over time, and that the present is the key to understanding the past.
