Pioneers Of Plate Tectonics 😊 Flashcards
1
Q
Order of pioneers (earliest to latest)
A
- Alfred Wegner
- Harry Hess
- Vine and Matthews
- Wilson
- McKenzie
2
Q
What did Wegner propose?
Did he have evidence to support it?
A
Theory of continental drift
5 pieces of evidence:
- Jigsaw fit
- Tectonic fit
- Fossil evidence
- Geological fit
- Glacial deposits
3
Q
What did Harry Hess propose?
What helped support his theory?
A
‘Sea floor spreading’ and ocean ridges
He used wegners theory of continental drift to support him
4
Q
What did Vine and Matthews do?
A
Provided evidence for ‘sea floor spreading’- paeleomagnetism
5
Q
What did Wilson discover?
A
Identified that hotspots could be found in the mantle and plates moved over the top of them to eventually create volcanic island chains
6
Q
What theory did McKenzie introduce?
A
‘Theory of Plate tectonics’ using previous work of geologists
