But A. Wegener did not have the specialisation to correctly weight the quality of the geophysical data and the paleontologic data, and its conclusions. Wegener's main interest was meteorology, and he wanted to join the Denmark-Greenland expedition scheduled for mid 1912. So he hurried up to present his Continental Drift hypothesis. [2]
Tectonophysics, a branch of geophysics, is the study of the physical processes that underlie tectonic deformation. This includes measurement or calculation of the stress - and strain fields on Earth’s surface and the rheologies of the crust , mantle , lithosphere and asthenosphere .

To begin with, the terminology and definition of what constituted geological study had to be worked out. The term "geology" was first used technically in publications by two Genevan naturalists, Jean-André Deluc and Horace-Bénédict de Saussure , [ 18 ] though "geology" was not well received as a term until it was taken up in the very ...
The divergent movement of the European and African plates was relatively short-lived. When the Atlantic Ocean formed between Africa and South America (about 100 Ma) Africa began moving northeast. As a result of this process, the soft layers of ocean sediment in the Alpine Tethys Oceans were compressed and folded as they were slowly thrust ...
Portuguese and Spanish explorers systematically measure magnetic declination to estimate the geographical longitude [3] [4]; 1556 – Agricola publishes De re metallica.This book acts as the standard mining and assaying text for the next 250 years.
It was used occasionally in the next few decades, but did not catch on until journals devoted to the subject began to appear, beginning with Beiträge zur Geophysik in 1887. The future Journal of Geophysical Research was founded in 1896 with the title Terrestrial Magnetism .
