Charles Darwin made a significant assertion regarding the formation of the Weald, a region in southern England that encompasses Kent, Surrey, and Sussex. According to his calculations, he estimated that the geological processes responsible for shaping the landscape took an astonishing 306,662,400 years to complete. This timeframe reflects Darwin's work on understanding the Earth's geological history and the immense timescales involved in such natural processes.

In Bill Bryson's book "A Short History of Nearly Everything," this information highlights the intricate relationship between time and geological changes. The vast duration that Darwin proposed underscores the complexity and gradual nature of the Earth's evolution, giving readers insight into how such regions have been sculpted over millions of years through various natural forces.
