Who Discovered Sea Floor Spreading

The man who discovered seafloorspreading and proposed his hypothesis on seafloor spreading. Part of his mission had been to study the deepest parts of the ocean floor.

This theory later became known as Sea Floor Spreading.

Who discovered sea floor spreading. Hess proposed that the seafloor was spreading as magma erupted from Earths interior along the oceans mid-ocean ridges. Harry Hammond Hess was an American geologist and a United States Navy officer in World War II who is considered one of the founding fathers of the unifying theory of plate tectonics.

The hot magma at the ridge erupts as lava that forms new seafloor. A process by which new seafloor ismade at the mid-ocean ridge. In this hypothesis hot buoyant mantle rises up a mid-ocean ridge causing the ridge to rise upward.

This created new seafloor which then spread away from the ridge in both directions. In 1962 Harry Hess proposed seafloor spreading as a way toexplain the lack of accumulated sediment. Following this new scientific buzz Harry Hess a United States Navy officer who served in World War II and geologist introduced his own theory of seafloor spreading.

The newly created seafloor slowly spreads away from the ridges and later sinks back into Earths. Mantle convection is the slow churn ing motion of Earths mantle. His theory followed that magma from the mantle could ooze up at mid oceanic rides and cool thereby expanding and pushing the plates on either side of the ridge away from it.

Harry Hess 1906-1969 an American geologist and professor of geology at Princeton University discovered seafloor spreading. Harry Hess was a geologist. Scientists brought these observations together in the early 1960s to create the seafloor spreading hypothesis.

This theory later became known as Sea Floor Spreading. Harry Hess argues that the continents had once been one and have drifted apart. Harry Hammond Hess a geologist and Navy submarine commander who later rose to the rank of Rear Admiral proposed the theory of seafloor spreading.

Hess believed that ocean trenches were the locations where ocean floor was destroyed and recycled. Based on material brought up from the ocean floor during a drilling project he determined that rocks on the ocean floor were younger than those on the continental landmasses. Hess proposes sea-floor spreading 1960.

The seafloor spreading hypothesis was proposed by the American geophysicist Harry H. Hess envisaged that oceans grew from their centres with molten material basalt oozing up from the Earths mantle along the mid ocean ridges. Seafloor spreading and other tectonic activity processes are the result of mantle convection.

The man who discovered sea floor spreading was Harry Hess. He is best known for his theories on sea floor spreading specifically work on relationships between island arcs seafloor gravity anomalies and serpentinized peridotite suggesting that the. Also to know is how did Harry Hess discover seafloor spreading.

In 1946 he had discovered that hundreds of flat-topped mountains perhaps sunken islands shape the. Seafloor spreading is a geologic process in which tectonic plate slarge slabs of Earths lithosphere split apart from each other. When the lava cools the magnetite crystals take on the current magnetic polarity and as more lava erupts it.

We know that the fastest moving plates the ones spreading the fastest have very long. Tony Watts an Oxford geologist and a convener of this weeks Plate Tectonics at 50 conference explains. He also discovered rocks on the ocean floor varied in age.

He published The History of Ocean Basins in 1962 in which he outlined a theory that could explain how the continents could actually drift. Who discovered seafloor spreading. Jobs EducationEarth SciencesPlate TectonicsScienceScientistsGeologyVolcanoesIcelandBiology.

There were older rocks farther from the mid-ocean ridges and younger rocks around mid-ocean ridges. He proposed that the continental movement is a.
