p. 474. Landscapes, tectonics, and climate
- Andrew Goudie

‘Landscapes, tectonics, and climate’ outlines the two biggest influences on landscapes — what a landscape looks like is, to a large extent, a result of tectonics and climate change. Since the acceptance of plate tectonic theory (1960s), scientists have been able to explain how mountains were built, rocks formed, oceans created, lakes sunk, and volcanoes subdued. How has climate changed over geological time? Climate change takes place over vastly different timescales: glaciers have reduced to one third of the level they were 20,000 years ago; the Little Ice Age took place between 1500 and 1850; the dust bowl in America (1930s) had a devastating impact in just a few years.
