Total questions: 10
Worksheet time: 5mins
Why did scientist reject Wegener's idea of continental drift?
it did not provide a force to cause plate motion
they thought it was a fairytale
his idea didn't account for gravity
Wegener's idea had nothing wrong with it
How were mid-ocean ridges discovered?
a satellite
submarine
surveys of the ocean floor done by a ship
divers
Why are magnetic patterns important evidence for plate tectonics?
the patterns show the waves' movement
it proves that new ocean floor moves away from the center of an ocean ridge
magnetic patterns do not support plate tectonics
