An isochron is a line on a map that connects points that have the same age. An isochron map of the ocean floor supports the theory of seafloor spreading because it shows the older rock near the deep sea trenches and the younger rocks near ocean ridges.

How does seafoor age and magnetic clues support seafloor spreading?

Seafloor is youngest near the mid-ocean ridges and gets progressively older as you move away from the ridge. Magnetic stripes on the seafloor provide evidence of seafloor spreading, as they show alternating patterns of normal and reversed magnetic polarity that match the Earth's magnetic reversals over time. This supports the theory of seafloor spreading as new oceanic crust is created at the mid-ocean ridge and spreads outward.


How do the ages of the rocks on the seafloor 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 do scientists now know about earth that would have answered the scientists who rejected wegeners theory?

Scientists now know about plate tectonics, which explains how Earth's outer shell is divided into large plates that move and interact with each other. This understanding supports Wegener's theory of continental drift, as it provides a mechanism for the movement of continents over time. Additionally, evidence from ocean floor mapping, seafloor spreading, and magnetic striping further supports the concept of plate tectonics.


How does the age of rocks in the seafloor provide evidence of seafloor spreading?

The age of rocks gets progressively younger as you move away from the mid-ocean ridges, where seafloor spreading occurs. This supports the theory of seafloor spreading, as new crust is being formed at the ridges and then moves away from them over time. This process leaves a record of older rocks further from the ridges and younger rocks closer to them.

What evidence in rocks supports the theory seafloor spreading?

Convergence supports the theory of seafloor spreading. Samples of the deep ocean floor are evidence of seafloor spreading because the basaltic oceanic crust and overlapping sediment become younger as the mid-ocean ridge is approached. Also, the rock that makes up the floor of the ocean is younger than the continents.

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


How ages of the rocks on the ocean floor supports the theory of seafloor spreading?

the ages of the rocks become increasingly older in samples obtained farther from the ridge and the younger had just come out the ridge.

Who had the theory of sea floor spreading?

Harry Hess came up with the theory of seafloor spreading . Alfred Wegener came up with the idea of continental drift NOT sea-floor spreading.

What are the similarities of the continental drift theory sea floor spreading and the plate tectonics theory?

the similarities of this 3 theory is,,,, they are all theory....

What does seafloor spreading have to do with the theory of continental drift?

Seafloor Spreading helped move the Continents to their current location.
