What are three kinds of evidence scientists have found to support ocean floor spreading?

1. Paleomagnetism. 2.(Thickness of the beds) Samples of the deep ocean floor show that basaltic oceanic crust and overlying sediment become progressively younger as the mid-ocean ridge is approached, and the sediment cover is thinner near the ridge. 2. (Age of the sea-floor) The rock making up the ocean floor is considerably younger than the continents, with no samples found over 200 million years old, as contrasted with maximum ages of over 3 billion years for the continental rocks. This confirms that older ocean crust has been reabsorbed in ocean trench systems. 3. (Geologic Activities) Study of the fracture zones that offset the sections of the ridge.

What are pieces of evidence that support the idea of Pangaea?
Continental Fit, Fossil Evidence and Sea floor Spreading. I just did this in science a month ago. :)
How does evidence that rocks farther from a ridge are older than rocks closer to the ridge support the idea of sea floor spreading?
;klh
The ocean floor spreading from the ridge what are three kind of evidence scientist have found to support this ideas?
the oceanic crust goes down your mouth
Used as evidence for sea-floor spreading?
magnetic reversal
Magnetic striping of evidence of?
Magnetic reversals and sea floor spreading.
What are three kinds of evidence scientists have discovered to support the idea of the ocean floor spreading?
molten material, magnetic stripes, and the ages of the rock.

Is the analysis of seafoor sediments evidence of sea-floor spreading?
Not really but sea floor sediments thickness increase with increased distance from spreading centers which is good evidence. Other evidence such as magnetic reversals, temperature, dating methods provide the best evidence of seafloor spreading
What are three types of evidence provided support for sea-floor spreading?
Seismic Waves, Rock formations, and the shapes of the continents over time
The ocean floor spreading from the ridge what are three kind of evidence scientist have found to support this ideas?

How do the ages of rock on the ocean floor support the theory of seafloor spreading?
The ages of the rocks become older the farther the way they are from the ridges. The closer they are the younger it is. This leaves evidence to the seafloor spreading theory.

What is sea floor spreading and what evidence do we have to prove it is happening?
Magnetic minerals on the ocean floor.
What is used as evidence for sea floor spreading?
Magnetic reversals
Used as evidence for sea-floor spreading?
magnetic reversal
What three types of evidence provided support of the theory of sea-floor spreading?
three are : eruptions of molten material magnetic stripes in the rock of the ocean floor and the ages of the rocks themselves :)
