How is continental drift supported by sea floor spreading?
as the sea floor spreads, this creates continental drift. think of it as a treadmill. as the band goes around and around whatever is connected to it goes with. this is the same as seafloor spreading and continental drift. the treadmill represents the sea floor spreading and the object on it the continent.
Harry Hess was an American geologist who studied sea-floor spreading. Alfred Wegener was a German scientist who studied continental drift. Sea-floor spreading made mid-ocean ridges and continents drift apart. Because of Hess's observation, many scientists began to have second thoughts about rejecting Wegener's hypothesis.
Answer: Continental drift is the hypothesis that states that the continents once formed a single landmass(Pangaea) broke up and drifted to their present locations.Sea-floor spreading the process by which new oceanic lithosphere(sea floor) forms as magma rises to Earth's surface and solidifies at a mid-ocean ridge.
They think a possible cause of continental drift is because of seafloor spreading and the water currents below the continents. +++ You are sort of on the right track, but not near enough to have helped the 9 people Answers had already counted! Sea-floor spreading is part of continental drift, and the currents are not in water, but in the viscous rock Mantle.
In sea-floor spreading, the sea floor spreads apart along both sides of a mid-ocean ridge as new crust is added. As a result, the ocean floors move like conveyor belts, carrying the continents along with them. Several types of evidence supported Harry Hess's theory of sea-floor spreading: eruptions of molten material, magnetic stripes in the rock of the ocean floor, and the ages of the rocks themselves. Harry Hess was an American geologist was one…
Arthur Holmes was a strong advocate of Alfred Wegener's theory of continental drift at a time when it was considered very controversial as there was no known mechanism which could allow this to occur. Holmes proposed that there was mantle convection allowing dissipation of heat from the core and that these convection cells could be a driving force of continental drift. This theory was ultimately incorporated into the modern understanding of sea floor spreading that…
