Sir william logan = first to systematically describe the geology of canada. Managed a coal mine and copper smelt venture. His maps introduced a cross-section a hypothetical vertical slice through the land. Looking at the minerals in canada (rocks, soils, etc. ) he made a layout of the geology of canada. Highest canada"s mountain named after him (mount logan) What changes controlled the evolution of life forms: positioning of the continents, extraterrestrial processes (ex. Supercontinent called pangea an assemblage of all the continents o o. Believed that pangea broke up into smaller continents that drifted apart to their present locations. Could not explain continental movement and how it happened (theory rejected) Young active volcanic islands stuck in the middle of oceans o: resulted from a moving plate drifting over a stationary magma plume in the mantle.
