Seafloor spreading provided evidence for continental drift by showing that new oceanic crust is formed at mid-ocean ridges, pushing older crust away. This process helped explain how continents could move and supported the idea of plate tectonics. The pattern of magnetic stripes on the seafloor also matched with predictions based on the movement of continents, further supporting the theory of continental drift.
What else can I help you with?
What did the magnetic strips prove in seafloor spreading?
They proved that the seafloor was spreading.
What discovery helped to prove that alfred wegner's theory of continental drift was possible?
The discovery of seafloor spreading and magnetic striping on the ocean floor in the 1960s provided compelling evidence for Alfred Wegener's theory of continental drift. This process showed how new oceanic crust is formed at mid-ocean ridges and helps move the continents apart, supporting the idea that continents are not fixed but can drift over time.
How did seafloor spreading help prove continental drift was true?
Evidence for continental drift is now extensive. Similar plant and animal fossils are found around different continent shores, suggesting that they were once joined. The fossils of the freshwater crocodile, found both in Brazil and South Africa, are one example; another is the discovery of fossils of the aquatic reptile Lystrosaurus from rocks of the same age from locations in South America, Africa, and Antarctica. There is also living evidence --- the same animals being found on two continents. An example of this is a particular earthworm found in South America and South Africa. The complementary arrangement of the facing sides of South America and Africa is obvious, but is a temporary coincidence. In millions of years, seafloor spreading, continental drift, and other forces of tectonophysics will further separate and rotate those two continents. It was this temporary feature which inspired Wegener to study what he defined as continental drift, although he did not live to see his hypothesis become generally accepted. It's generally saying that fossils have been found on landmasses far away from each other but because of seafloor spreading the continents could have once been connected.
How does seafloor spreading help scientists explain continental drift?
If one can prove that the sea floor spreads out from the mid oceanic ridges, then logically the continents must be moving apart to accommodate the spreading. Conversely there must also be places where sea floor is being destroyed if the Earth is to stay the same size.
Why was the theory of seafloor spreading rejected?
The theory of seafloor spreading was not rejected; in fact, it is widely accepted in the field of geology. Proposed by Harry Hess in the early 1960s, seafloor spreading explains how new oceanic crust is formed at mid-ocean ridges and then moves away as tectonic plates drift apart. This concept revolutionized our understanding of plate tectonics and the Earth's geology.
What are 3 things of evidence that scientists have that prove the ocean is spreading?
1) seafloor spreading 2) continental drift 3 i only found 2
Did seafloor spreading prove the theory of continental drift?
Yes, seafloor spreading provided concrete evidence for the theory of continental drift proposed by Alfred Wegener. It demonstrated that new oceanic crust was continuously forming at mid-ocean ridges, pushing the continents apart over time. This supported the idea that continents were once connected and have since moved to their current positions.
What is seafloor spreading that ''helps'' the theory of continental drift?
How seafloor spreading helps to explain the theory of continental drift is that wegener couldn't explain why and waht force caused the continents to move and so seafloor spreading helps to explain the theory of continental drift because it shows the force that made the continents move and that was te only thing that wagener needed to prove his theory of continental drift............thanks

What is the 5 pieces to prove contenential drift?
Fit of continents: The edges of continents like South America and Africa fit together like puzzle pieces. Fossil evidence: Similar fossils of plants and animals found on different continents suggest they were once connected. Rock formations: Matching rock formations and mountain ranges across continents support the idea of continental drift. Paleoclimate data: Evidence of past climates, such as glaciers in regions that are now tropical, can be explained by continental drift. Seafloor spreading: Mid-ocean ridges and magnetic striping on the seafloor provide evidence of tectonic plate movement and support the theory of continental drift.

What is Alfred wengeners first discover as an scientist?
Alfred Has Been Working On The Contintal Drift For A Long Time And Scientist Are Stilll Trying To Prove The Continental Drift. So The Continental Drift Is His First Discovery...,(:.!? --- Jocelyn !!
Why were most scientists disagreeing with Alfred Wegeners continental drift theory?
There was no evidence to prove it
What three pieces of evidence did Harry Hess gather to prove that seafloor spreading was taking place?
Magnetic stripes on the seafloor showed alternating patterns of normal and reversed polarity, matching Earth's magnetic field reversals. Age dating of seafloor rocks revealed that rocks were youngest along mid-ocean ridges and oldest near continental margins. Sediment thickness on the seafloor was thinnest at mid-ocean ridges and thickest near the continents, supporting the idea of seafloor spreading.
