- 3 famous theories
- this theory is introduced by Alfred Wegener
- this theory suggests that all the continents were joined into a single large mass called supercontinent pangaea
- what is the supercontinent called
- meaning of pangaea
- the supercontinent pangaea is surrounded by the ocean called
- the large mass broke into two large masses called
- what is in between laurasia and gondwanaland
- 4 evidences of continental drift theory
- what are the two animal fossils found in south america and african continents
- what is the fern fossil that were found in other continents
- what fossil is great for swimming to transverse oceans
- in evidence 3, what two mountains matched in sedimentary layers
- where did wegener die?
- all rocks are formed from deposition from the primordial ocean
- all rocks are formed by igneous processes
- after the rejection of wegener's theory, he proposed what
- who propsoed seafloor spreading theory
- who coined the seafloor spreading theory
- (temp where magnetic minerals change magnetic behavior), these minerals are randomly oriented.
- is the record of Earth’s magnetic field through time.
- refer to the shifting of the pole’s polarity over timE
- were also used to determine the presence of submarines
- 7 major plates
- 8 minor plates
- moving continent will retain a record of changing paleomagnetic directions through time that reflect the changing orientations and distances to the pole
- The resulting path of observed pole positions
- and oceans rests on
- other term for tectonic plate
