Who were the two scientists who proposed the theory of seafloor spreading in early 1960s?

While two people proposed continental drift (Alfred Wegener and Alexander du Toit), it was just ONE scientist Harry Hess that proposed the mechanism of sea floor spreading to explain how the continents actually moved.


Who proposed the theory of seafloor spreading based on maps of the ocean floor?

The theory of seafloor spreading was proposed by Harry Hess, a geologist and Navy officer, in the early 1960s. He proposed that new oceanic crust is formed at mid-ocean ridges and then spreads outward. This theory helped to explain the mechanism behind continental drift and plate tectonics.

What does seafloor spreading have to do with the theory of continental drift?

Seafloor Spreading helped move the Continents to their current location.


What scientist used sonar to prove seafloor spreading under the Atlantic ocean?

Harry Hess, an American geologist and Navy officer, used sonar to study the seafloor of the Atlantic Ocean. He discovered the presence of mid-ocean ridges and proposed the theory of seafloor spreading in the early 1960s, which played a crucial role in the development of the theory of plate tectonics.


Did seafloor spreading prove the theory of continental drift?

Yes, seafloor spreading provided concrete evidence for the theory of continental drift proposed by Alfred Wegener. It demonstrated that new oceanic crust was continuously forming at mid-ocean ridges, pushing the continents apart over time. This supported the idea that continents were once connected and have since moved to their current positions.


Theory proposed by Harry Hess that includes processes along mid-ocean ridges?

The theory proposed by Harry Hess is called seafloor spreading. It suggests that new oceanic crust is formed at mid-ocean ridges through the upwelling of magma from the mantle, pushing older crust aside. This process contributes to the continuous movement of tectonic plates and plays a key role in the theory of plate tectonics.


When did harry hess propose seafloor spreading?

Harry Hess proposed the idea of seafloor spreading in the early 1960s, with his initial proposal being presented in 1960. This concept revolutionized our understanding of plate tectonics and the movement of the Earth's lithosphere.

The Seafloor Spreading Theory


How do the ages of the rocks on the ocean floor support the theory of seafloor spreading?

The ages of the rocks become older the farther the way they are from the ridges. The closer they are the younger it is. This leaves evidence to the seafloor spreading theory.
