What is the evidence for plate movement

What evidence did Alfred Wegener have for continental drift, and what evidence was there to support the Hess theory of seafloor spreading?

Alfred Wegener's evidence was the fit of the continents and glacial till deposits. While the continents were moving, the sea floor was moving with it.

Rylan N said...

The evidence for continental drift was glacial deposits in the tropics, also fossils that don't match climate. The evidence for seafloor spreading is the oceanic crust gets thinner near the mid ocean trench.

Gareth B said...

One source of evidence was that of paleomagnetism.

Evan L said...

Alfred Wegener's evidence was he found fossils in areas that didn't match the climate and that the continents looked like they fitted together like a puzzle.And Hess's was that while they were moving the sea floor was moving with it.

Brendan S said...

He used the similarity of South American and African coasts to concur with predecessors and support his theory that the continents were once one mass. And while the continents were moving the sea floor was moving with it.

Nothing could feel more solid than the ground under our feet. Yet the surface of the Earth is not fixed, but rather broken up like a jigsaw puzzle into enormous plates that move. This process is called plate tectonics, and it transformed the thinking of geologists. One of them, Harry Hess, was an instrumental figure in figuring out how plate tectonics worked.
Hess possessed two valuable skills: careful attention to detail and the ability to form sweeping hypotheses. This unusual combination produced groundbreaking work on a number of subjects, including the origin of ocean basins and island arcs, mountain building, and the movement of continents. The idea that the continents might have moved, or “drifted” over time can be traced back to the sixteenth century, when European cartographers compiled world maps based on the seagoing expeditions of that time. This idea was transformed into the theory of “continental drift” by German meteorologist Alfred Wegener in 1912, when he published a treatise with several lines of supporting evidence that went beyond simply matching the continents like puzzle pieces. These lines of evidence included, for example, matching geological formations and paleontological distributions from South America and Africa. Wegener’s critics correctly pointed out, however, that the continents could not simply “plow” though the ocean floor as Wegener had vaguely theorized. It was Hess who determined how oceanic mountain ranges, called mid-ocean ridges, are fundamental to the tectonic movement that results in the drift of continents.

Actually there is a lot of evidence that supported his theory the big one was fossils of animals on distant continents and plants for example Glossopteris was one the strange reasons that Alfred was more than ever to prove his point.

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.

Alfred's evidence was that the continents fit together like a puzzle. Hess's evidence was seafloor spreading and it helped Alfred's theory.

Jack D said...

Alfred Wegener's and everything was moving the water the earth for example what was moving is Glacial , Till , Deposits on the sea and ocean floor.

THIS IS BRANDON GALLANT the acer will not work so im use in gareths...one was paleomagnetism.

there was a lot of evidence including fossils till glaciers and stuff like that.

Noah R said...

He didn't have much evidence, but here was one thing; paleomagnetism.

Anonymous said...

The evidence is that there were some warm temperature fossils, in a cold climate, and cold climate fossils, in a warm temperature.

Ella T. said...

Alfred's evidence was the fit of the continents, animals and fossils not belonging in that sort of climate, rocks the same type, and age spread out on the different continents, and..... Yeah... on to that Hess dude! The Hess dude had the theory of seafloor spreading, some people sent down a submarine called the... don't remember..... but still, they found new rocks in the mid ocean place, and old rocks were around that area....

taylor said...

fossils, glaciers, and rocks.

Cassie M said...

The evidence that he had was Glaciers, Fossils and Rocks. He thought that continetal drfit was caused by the spin of the Earth.

In the 1900's, a German meteorologist by the name of Alfred Wegener was the first to present an argument supporting continental drift. He proposed that the continents were not stationary, but actually moving or drifting away from one another. His primary sources of evidence included the fit of the continents, glacial till deposits, and the apparent shifting of climatic belts over time. His colleagues at the time argued for polar wandering as an explanation of his data. These ideas were not well accepted until later scientists in the 1940's and 50's expanded on these ideas adding to them paleomagnetism, convection currents and sea floor spreading. With all this new evidence, plate tectonic theory became an accepted idea in the 1970's.

His evidence was that animals were found somewhere other tan their climate, glacial till, and how the continents fit together like puzzle pieces. The sea floor was moving with the continents.

That fossils and rocks were in the wrong climates.

I think you just copied mine.....It is the one above yours and it has the same grammatical errors......Please don't copy paste mine next time.......Come up with at least with different wording than me......
