How do rocks along the central valley of the mid-ocean ridge provide evidence of sea- floor spreading?
they can leave marks to prove that they have existed
Who Used sonar to prove sea floor spreading?
Harry Hess
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
What are the three things Alfred Wegener used to prove his theory about pangaea?
Fossils, Climate, and Sea-Floor Spreading
In 1960 harry hess proposed the theory of?
sea floor spreading. that the sea floor was spreading and there for pushing the continents .he continued studying Alfred Wegener's theory and became more knowledgeable about then started gathering information to prove the theory and did
What tools were used to prove seafloor spreading?
Tools such as sonar mapping, geologic sampling, and paleomagnetism studies were used to provide evidence for seafloor spreading. Sonar mapping allowed for the creation of detailed maps of the ocean floor, revealing features such as mid-ocean ridges and deep-sea trenches. Geologic sampling involved collecting rock samples from the ocean floor to study their age and composition. Paleomagnetism studies focused on analyzing the alignment of magnetic minerals in rocks, providing evidence of past changes in Earth's magnetic field that support the idea of seafloor spreading.
What three pieces of evidence did Harry Hess gather to prove that seafloor spreading was taking place?
Three evidence that supports Harry Hess theory of Seafloor Spreading is; 1. Paleomagnetism. 2. Plate Tectonics. 3. Polar Wondering and Polar Reversal.
Why was the theory of seafloor spreading rejected?
Because he wasn't able to prove it he said that if the ocean floor is moving, then the continents might be moving also
What did the magnetic strips prove in seafloor spreading?
They proved that the seafloor was spreading.
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.
Did seafloor spreading prove the theory of continental drift?
Seafloor spreading helped prove the theory of continental drift. Pangea theory also helped.
What evidence did harry hess use to prove sea-floor spreading?
Harry Hess was mapping the floor of the ocean when he found a mountain range in the middle of the ocean. He found that the land nearest to the ridge was younger compared to the fact that the farther away land was from the ridge, the older it dated. He used this to find that the mountain ridge was creating new land and pushing aside the old land.
