Archibald Geikie Biography

Scottish geologist Archibald Geikie championed the theory of land surface erosion through fluvial action, weathering agents, and ice during repeated ice ages, overturning the prevailing view of submarine sculpting. He also investigated past volcanic activity, chronologically organizing Scotland's eruptions and recognizing major unconformities in its ancient sandstone strata. His extensive writings included foundational textbooks on geology, biographies of fellow scientists, and explorations of geological landscapes and volcanic history, solidifying his legacy as a pivotal figure in Earth sciences.
