The theory that continents move apart from each other?
Continents are not tecnically moving 'away' from each other, they are just moving. This is due to the sub continent plates and the volcanic activity in the ocean. As new volcanic matter from the earths core comes to the surface it pushes continental plates apart.
What is the difference of seafloor spreading and continental drift?
In continental drift it says that they were drifted apart by the spin of the earth and in seafloor spreading the earths crust is drifted apart by the ridges in the mid-ocean.
Do the sinking of mid-ocean ridges into the ocean trenches prove the Continental Drift theory?
The discovery of the mid-ocean ridge confirmed Alfred Wegener's hypothesis that the continents were moving,
What was determined to be the mechanism by which continents spread apart?
Upwelling of lava at the mid-ocean ridges.
Was used to by Wegner to establish continental drift?
He hypothesized that the continents plowed through the ocean floor pushed by the spin of the Earth. Wegener used continental drift to explain evidence of changing climates.
Why are the continents and the ocean floors moving?
Contienental drift, which is when under the surface magma spreads apart and streches the crust apart.
The primary source that causes the seafloor to spread and continents to drift?
In the middle of the ocean is a rift where the ocean floor squeezes out lava and pushes the ocean plates apart.
Why is the Alantic Ocean expanding?
because the continents are drifting further apart due to th oceantal crust separating under water

What is a continental shift?
Continental drift is the idea that Wegener created, that all the continents were once a single landmass which he called Pangaea, and they have since drifted apart.
Anu ang Continental Drift?
Continental Drift is a speculation made in 1596 by Abraham Ortelius. He stated that continents drift across the ocean bed.
Which ocean is getting bigger and which one is getting smaller?
The Atlantic Ocean is getting bigger and the Pacific Ocean is getting smaller. This is caused by the continental drift. The continental drift is the movement of the continents. Since the continents move 1 centimeter per year the crack in the middle of Atlantic is the mid ocean ridge. Magma is bubbling out and is adding to the ocean floor causing the continents to push away.
What is the difference of seafloor spreading and continental drift?

Why would the fossil of an ocean fish found on two different continents not be good evidence for continental drift?
lol

Why the fossils of an ocean fish found on two different continents would not be good evidence of continental drift?
Because there's really just one big ocean. A fish would be able to travel ANYWHERE in it. well, because of Pangaea, the continents where in a huge "blob" so when the first fish where created, there where some on the eastern south America and western Africa, when the continents moved apart with the time, there where still some fossils of those specific animals, ocean animals in this case...
