Seafloor spreading The idea that the seafloor itself moves (and carries the continents with it) as it expands from a central axis was proposed by Harry Hess from Princeton University in the 1960s.t the Mid-Atlantic Ridge (and in other areas), material from the upper mantle rises through the faults between oceanic plates to form new crust as the plates move away from each other, a phenomenon first observed as continental drift.

- Harry Hammond Hess, a professor of geology at Princeton University, was very influential in setting the stage for the emerging plate-tectonics theory in the early 1960s. He be … lieved in many of the observations Wegener used in defending his theory of continental drift, but he had very different views about large-scale movements of the Earth.

Wegener and Continental Drift Theory The reaction to Alfred Wegener's Continental Drift Theory demonstrates that new ideas threaten the establishment, regardless of the century. Alfred Wegener was the scientist who proposed the Continental Drift Theory in the early twentieth century.Simply put, his hypothesis proposed that the continents had once been joined, and over time had drifted apart.egener did not even present Continental Drift as a proven theory. He knew he would need more support to convince others. His immediate goal was to have the concept openly discussed. These modest goals did not spare him.

The Plate Tectonics Theory The plate tectonics theory is a combination of two other theories: continental drift and sea-floor spreading. Alfred Weneger, a German meteorologist, first hypothesized about continental drift in 1912.

How did Glomar Challenger help support seafloor spreading? Challenger showed that the sea floor in the atlantic was younger then than the crust in Soputh America and Africa, proving seafloor spreadingand continental drift.

- - Plate Tectonics Theory is the combination of Continental Drift and Ocean/Sea Floor Spreading. BTW. The scientist who started it is Howa … rd Baker continued by Alfred Wegener.ne, that gravitational forces of the moon and sun cause the earth's tides and also the movement of continents across the globe. Also, that larger and sturdier continents broke through thinner oceanic crust. Not 100% sure, but thats what my book says.

seafloor spreading Abundant evidence supports the major contentions of the seafloor-spreading theory. First, samples of the deep ocean floor show that basaltic oceanic crust and overlying sediment become progressively younger as the mid-ocean ridge is approached, and the sediment cover is thinner near the ridge.irst, samples of the deep ocean floor show that basaltic oceanic crust and overlying sediment become progressively younger as the mid-ocean ridge is approached, and the sediment cover is thinner near the ridge.

Continental Drift Theory and Plate Tectonic Theory CONTINENTAL DRIFT THEORY. In the early 20th century, German scientist Alfred Wegener published a book explaining his theory that the continental landmasses, far from being immovable, were drifting across the Earth.

Who discovered Pangaea? Well, he discovered that all the Continental were once joined together. In 1912 a German meteorologist named Alfred Wegener (1880-1931) hypothesized a single pronto-super con … tinent that divided up into the continents we now know because of continental drift and plate tectonics.

- Seafloor spreading. Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge.eafloor spreading helps explain continental drift in the theory of plate tectonics. When oceanic plates diverge, tensional stress causes fractures to occur in the lithosphere.

Evidence for Sea-Floor Spreading Evidence From Magnetic Stripes. When scientists studied patterns in the rocks of the ocean floor, they found more support for sea-floor spreading. You read earlier that Earth behaves like a giant magnet, with a north pole and a south pole. Surprisingly, Earth’s magnetic poles have reversed themselves many times during Earth’s history.

Democracy in Indonesia, between ISIL and elections In light of this, the call by Indonesia’s ISIL supporters to rally followers in support of an Islamic State, with tales of ISIL violence spread around as the “success stories” of some kind of holy war, becomes a very real discomfort.

OCEAN FLOOR Marie Tharp, along with colleague Bruce Heezen, made the first detailed map of the ocean floor using sonar readings. In the late 1940s, Tharp discovered a rift valley running down the centre of the Mid-Atlantic Ridge, and came to realize that a chain of mid-ocean ridges circles the globe.

Who was Alfred Wegener and what was his theory? Biographical Note. German climatologist and geophysicist who, in 1915, published as expanded version of his 1912 book The Origin of Continents and Oceans. This work was one of the first to suggest continental drift and plate tectonics.

High School Earth Science/Continental Drift An important piece of plate tectonic theory is the continental drift idea. This was developed in the early part of the 20 th century, mostly by a single scientist, Alfred Wegener. His hypothesis states that continents move around on Earth's surface and that they were once joined together as a single supercontinent (Figure 6.5).

Continental Drift: Theory & Definition Plate tectonics is the widely accepted theory that Earth's crust is fractured into rigid, moving plates. In the 1950s and 1960s, scientists discovered the plate edges through magnetic surveys of the ocean floor and through the seismic listening networks built to monitor nuclear testing.art of the opposition was because Wegener didn't have a good model to explain how the continents moved apart. Though most of Wegener's observations about fossils and rocks were correct, he was outlandishly wrong on a couple of key points.

- During the 1940s and 1950s, scientists began using radar on moving ships to map large areas of the ocean floor in detail. The youngest rocks are found nearest to the mid-ocean ridges. The scientists Harry Hess invented echo-sounding devices for mapping the ocean floor. As the seafloor spreads apart, hot saltwater moves upward and flows from the cracks. As the new seafloor moves away from the ridge and becomes hotter, it moves upward and forms still higher ridges.

- Harry Hess came up with the theory of Sea-floor spreading. Alfred Wegner came up with the theory of Continental Drift and Arthur Holmes proposed a suitable mechanism for this to occur (mantle convection).

Seafloor Spreading Seafloor spreading is one of the two major processes of plate tectonics, the other being subduction. Seafloor spreading is the continuous process of forming new igneous rock at midocean ridges by injection of magma that forms new seafloor. The process is continuous because forces cause opposite sides of the midocean ridge to constantly move apart, making new room for the process to repeat.

Plate Tectonics Plate Tectonics. Plate Tectonics. Vine and Matthew's discovery of the magnetic striping on the sea floor showed that Hess' idea of sea-floor spreading was correct; oceans and continents moved together and the mid ocean ridges actually are areas where new ocean floor is created.

Evidence for Sea-Floor Spreading Evidence for Sea Floor Spreading. 1  In the 1960s scientists found evidence that new. material is erupting along the mid-ocean ridge. 2  The presence of pillow shaped rocks has showed. that molten material has erupted again and again.
