What did the magnetic strips prove in seafloor spreading?
They proved that the seafloor was spreading.
How are magnetic patterns in sea floor rock evidence of seafloor spreading?
Magnetic alignment of rocks, in alternating strips that run parallel to ridges, indicates reversals in Earth's magnetic field and provides further evidence of seafloor spreading.
What could wegener not satisfactorily explain about continental drift?
No
Which statement provides evidence that the seafloor is spreading out from both sides of the Mid-Atlantic Ridge?
parrell strips of igneous rocks on each side of the ridge show matching reversal of magnetic polity
Strips of alternating magnetic polarities found in rocks in the ocean basin?
provide evidence for sea-floor spreading

Why are the magnetic strips in the pacific ocean wider than the ones in the Atlantic ocean?
The Pacific seafloor formed at a faster spreading rate than the Atlantic seafloor.

How do you calculate the rate of seafloor spreading?
rate of spreading for stripe = width of stripe / time duration If a magnetic strips is 60 km wide and formed over 2 million years, then the rate at which spreading formed the was 30 km/m.y. The rate is equivalent to 3 cm/year. Spreading added an equal width of oceanic crust to a plate on the other side of the mid-ocean ridge, so the total rate of spreading across the ridge was 60 km/m.y. (6 cm/year), a typical rate of seafloor spreading.
What do the sea floor spreading strips stand for in the paper model?
ahh
