Landforms and their Evolution — Key Cases & Reports

Key Cases & Reports

Theory of Uniformitarianism (James Hutton, Charles Lyell)

Late 18th - Early 19th Century

This fundamental principle, encapsulated by Hutton's phrase 'the present is the key to the past,' revolutionized geological thought. It posits that the same natural laws and…

Geographical Cycle / Cycle of Erosion (W.M. Davis)

Late 19th - Early 20th Century

William Morris Davis proposed a conceptual model for landform evolution, suggesting that landscapes pass through distinct stages of 'youth,' 'maturity,' and 'old age.' He argued…

Theory of Plate Tectonics (Various contributors, mid-20th Century)

Mid-20th Century (1960s onwards)

This unifying theory explains the large-scale motion of Earth's lithosphere. It posits that the Earth's outer rigid layer (lithosphere) is broken into several large and small…

Dynamic Equilibrium Theory (John T. Hack)

1960s

Proposed as an alternative to Davis's cycle, this theory suggests that landscapes are in a state of dynamic equilibrium where uplift and erosion rates are balanced, leading to…
