Record 1 2009-04-21

English

Subject field(s)
  • Plate Tectonics
DEF

The hypothesis that the continents had once formed a single landmass before breaking apart and drifting to their present locations.

CONT

The hypothesis of continental drift was largely developed by the German Alfred L. Wegener, a lecturer in astronomy and meteorology, who suggested that the Earth's continents had at one time been joined in two supercontinents. In the year 1912, Wegener made the proposal that all the continents were previously one large continent, but then broke apart, and had drifted through the ocean floor to where they are now located.

OBS

The terms "drift theory" and "displacement theory" are the current shortened forms used implicitly to mean the "theory of continental drift", or "continental displacement theory".

OBS

displacement theory; Wegener hypothesis: terms used at Natural Resources Canada - Earth Sciences Sector.

CONT

[...] [les] débris végétaux qui ont évolué en charbon [...] provenaient [...] de forêts plus lointaines dont les produits étaient apportés par les eaux fluviales (théorie allochtone).

CONT

Le mécanisme de la formation de la houille conduit à deux hypothèses différentes : ou bien les végétaux, arrachés par les cours d'eau et transportés par les courants marins, sont allés s'engloutir loin de leur lieu d'origine (théorie de la formation par transport ou allochtone); ou bien les fonds lagunaires et marécageux s'enfonçant lentement et par à-coups, les forêts qui les bordaient se sont enfouies et décomposées sur place (théorie de la formation autochtone).

CONT

Théorie allochtone (de la formation du charbon).
