How does paleomagnetism provide support for the idea of sea floor spreading?
Wiki User
∙ 10y ago
Rocks that are found at on the sea floor of the Earth differ in magnetizations. Using paleomagnetism, these rocks were known to have preserved an imprint of the changes in the earths magnetism over long periods of geological time, which proved the theory of sea floor spreading.

What are three types of evidence provided support for theory of sea?
eruptions of molten material, magnetic stripes in the rock of the ocean floor, and the ages of the rocks themselves
How do echinoderms interact with creatures in their environment?
Echinoderms usually feed on smaller creatures in the sea floor. They also provide food for other larger fish within the ocean.
What is the predicate of The baby crawls across the floor?
across the floor.
Past tense of the dog lies on the floor?
The dog laid on the floor.

no
What do magnetic reversals help support?
the theory of sea-floor spreading
What magnetic reversals help support?
the theory of sea-floor spreading
Which was not included in the support for harry hess's hypothesis of sea-floor spreading?
Granitic strips in the ocean floor ... Novanet
Which was not included in the support for harry hess's hypothesis sea floor spreading?
Granitic strips in the ocean floor ... Novanet
How magnetic reversals provide evidence for sea floor spreading?
Because of the stripes at the sea floor which are magnetic minerals
How are earthquake patterns used to provide evidence of sea floor spreading?
By using a siesmograph.
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.
The ways that fossils helped support the hypothesis of continental drift?
Because of sea floor spreading
How sea floor spreading provide evidence for tectonic plates?
by the plate tectonic and the ocean bridges
What is a spreading center on the ocean floor?
sea floor-spreading..;)
What made the scientific community accept wegener's theory years later?
Alfred Wegener was the proponent of the Continental Drift Theory. The scientific community accepted this theory due to the phenomena of paleomagnetism, sea floor spreading and plate tectonics.
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.
