Morley worked on the theory of continental drift similar to work by Britons Fred Vine and Drummond Matthews. The three contributed significantly to geology by relating the magnetic properties of ocean crust to the processes involved in the theory of plate tectonics. Following graduate studies at the University of Toronto, Morley became Director of the Geophysics Branch of the Geological Survey of Canada in Ottawa (1950–1969). In 1970 he founded the Canada Centre for Remote Sensing and served as its Director General from 1971 to 1980.
