Briefly describe the theory of continental drift and include the name of the original land mass our current-?

Question

continents were once a part of it

Answer 1

Pangaea is the name of the original super-continent.

Plate tectonics describes how the continents move.

Answer 2

The original land mass that our continents were once part of is actually Rodinia (if by original you mean the fist). Rodinia broke up into separate continents and then they all came together again and that supercontinent was called Pangea, as others have mentioned.

As far as continental drift, that is an old theory (pre-plate tectonics). It incorporates that idea that the continents move around at the Earth's surface, which is also part of the current plate tectonics theory, but it lacks any REASON WHY the continents drift around. Plate tectonics does provide for a driving force for the plates in "mantle convection".

Answer 3

Don't waste your time with outdated theories like Continental Drift. The currently accepted theory is Seafloor Spreading and Plate Tectionic. Continental drift made some good observations such as the Continents fitting together like a jigsaw puzzle, and similar rocks could be found at the reconstructed locales, but it lacked a viable model as to what caused the continents to drift. Plate Tectonics provides that mechanism: Mantle Convection.

Answer 4

Pangaea is the name of the one big old supper Continent.

The theory is that all land mass is like Lilly's floating on a pond and will drift.

hey theres a thing called google, try using it instead of having people do your homework for you...also wikipedia.org
