What do magnetic reversals help support?
the theory of sea-floor spreading
How do ocean ridges and deep-sea trenches support the theory of sea floor spreading?
Sea Floor spreading has to do with the crust forming at ocean ridges and being destroyed at deep sea trenches.
What was dan mckenzie's hypothesis?
His hypothesis was continental drift and the sea floor spreading. He helped discover the 7 major plates and large unknown amounts of minor plates. Our plates drift 2 cm a year.
The difference between plate tectonics continental drift and sea floor spreading?
Answer:Continental drift is the hypothesis that states that the continents once formed a single landmass(Pangaea) broke up and drifted to their present locations.Sea-floor spreading the process by which new oceanic lithosphere(sea floor) forms as magma rises to Earth's surface and solidifies at a mid-ocean ridge.
How does evidence that rocks farther from a ridge are older than rocks closer to the ridge support the idea of sea floor spreading?

The ways that fossils helped support the hypothesis of continental drift?
Because of sea floor spreading
Summarize the ways that fossils helped support the hypothesis of the continental drift?
Because of sea floor spreading
What was Arthur Holmes' hypothesis?
Spreading ocean floor
What was the hypothesis of the sea-floor spreading?
excess nutrients in the water
What discovery led scientists to accept Wegeners continental drift hypothesis?
One day while scientists were exploring the sea floor, they discovered sea-floor spreading, thus proving Wegener's hypothesis to be correct.
What is the most important in providing support for the sea floor spreading hypothesis?
"Magnetic Polarity: the North and South magnetic poles have switched positions throughout Earth's history... the record of magnetic polarity in the rocks of the ocean floor provided unequivical support for the seafloor spreading hypothesis." - as quoted in chp. 4, pg. 94, from the textbook "The Good Earth: Introduction To Earth Science"
Wegeners hypothesis of continental drift was finally confirmed by?
evidence supporting the idea of sea-floor spreading.
What magnetic reversals help support?
the theory of sea-floor spreading
What do magnetic reversals help support?
the theory of sea-floor spreading
Describe how magnetism is used to support the theory of seafloor spreading?
New material is added to the sea floor when sea floor spreading occurs. When the iron cools it is magnetized by the magnetic field of the earth.
What was Alfred wegner's hypothesis for continental drift?
He thought that the world was once pangea but then the plates and "Sea Floor Spreading" moved Pangea around
