tectonics
... Wegener in the early 20th century is the forerunner to the modern theory of plate tectonics. It was based on the observation that many continents "fit together like a jigsaw puzzle" (e.g. S. America and Africa) and, if joined back together, many similarities exist in rock types, geologic structures ...

History of geodesy
Geodesy (/dʒiːˈɒdɨsi/), also named geodetics, is the scientific discipline that deals with the measurement and representation of the Earth. The history of geodesy began in antiquity and blossomed during the Age of Enlightenment.Early ideas about the figure of the Earth held the Earth to be flat (see flat earth), and the heavens a physical dome spanning over it. Two early arguments for a spherical Earth were that lunar eclipses were seen as circular shadows which could only be caused by a spherical Earth, and that Polaris is seen lower in the sky as one travels South.
