1What Unexplained Observations Had been Made About Earth?
- AFossils and similar plants have been found on Africa and South America, suggesting that they were linked in some way. The coastlines of these continents also matched very well. Fossils of Sea Creatures had also been found high in the Alps.
- BAliens.
- CBlack Magic.
2What Did Wegener Do?
- AHe looked into the rocks on the continents and found that the layers matched, as well as the fossils.
He came up with the theory of Continental Drift. - BEat
- CTalk
- AHe looked into the rocks on the continents and found that the layers matched, as well as the fossils.
3What is the Theory of Continental Drift?
- AThat 300 Million Years Ago there was a single Super Continent Called Pangaea. It then broke into multiple parts, and these have been drifting apart.
- BThat the Continents are all in a race and it's a drift race, so the continent that drifts the most will win.
4Why Was the theory of Continental Drift not accepted at first?
- APeople first believed in the 'Land Bridges' Theory, which this went Against. It was a big change and so most Scientists were hostile to the idea.
He couldn't explain why or how, he claimed it to be Tidal forces or Earth's rotation, but this was impossible.
Wegener was also a Meteorologist, not a proper Geologist. - BIt was fuckin' stupid.
- CIt's silly.
- APeople first believed in the 'Land Bridges' Theory, which this went Against. It was a big change and so most Scientists were hostile to the idea.
5Explain 'Seafloor Spreading'?
- AThe Mid-Atlantic Ridge shows that magma rises up through the sea floor, solidifies and forms underwater mountains, it suggested that the Seafloor Spreads by about a few cm a year.
- BThat the rock is moving due to the magnetic orientation of the rocks. As the magma comes out, iron particles in the rock tend to align to the Earth's Magnetic Field. Every half a million years, the magnetic field switches direction, - and he rock on either side of the ridge, has bands of alternate magnetic polarity, symmetrical to the ridge.
6What Other Evidence is there for Continental Drift?
- AThat the rock is moving due to the magnetic orientation of the rocks. As the magma comes out, iron particles in the rock tend to align to the Earth's Magnetic Field. Every half a million years, the magnetic field switches direction, - and he rock on either side of the ridge, has bands of alternate magnetic polarity, symmetrical to the ridge.
