Who had the sea floor spreading theory?
Harry Hess came up with the theory of seafloor spreading . Alfred Wegener came up with the idea of continental drift NOT sea-floor spreading.
Who had the theory of sea floor spreading?
Harry Hess came up with the theory of seafloor spreading . Alfred Wegener came up with the idea of continental drift NOT sea-floor spreading.
What patterns indicate sea floor spreading is occurring?
Ridges, parallel to the axis of spreading, are formed in the ocean floor as hot lava moves up to fill the gap then cools when it comes in contact with sea water.
Who came up with the theory of plates tectonics?
J.T Wilson was the one who came up with the theory of plate tectonics. Harry Hess came up with the theory of sea-floor spreading. Alfred Wegener came up with the theory of continental drift and Arthur Holmes proposed a suitable mechanism for this to occur (mantle convection).
What pushes up through rifts in the ocean floor and cools to form new sea floor?
sea floor spreading, boo. it's molten rockk from earth's coree. hope it helpped!! :)
Did Alfred Wegener make sea floor spreading?
He is credited with coming up with the theory of continental drift.
Are the rocks that make up the ocean floor older or younger than those that make up the continents?
same age. the ice caps just melted on top over the rocks at the bottom of the sea.
Does two plates moving apart cause sea floor spreading?
Yes, two tectonic plates moving apart can cause sea floor spreading. As the plates separate, magma rises up to fill the gap, solidifying to form new oceanic crust. This process contributes to the expansion of the ocean basins.
What cause a new sea floor to be created and how is it created?
Sea floor spreading causes this. As the floor spreads apart new magma is being pushed up through the ridge from the mantle through convection currents. It's like a recycling system.
How does sea floor spreading make the continents move?
Under the oceanic crust is the layer of the earth called the mantle. This layer is moving rock that is very, very hot! As the hot material in the mantle pushes up through the crust in the sea floor, it cools and becomes new crust as it pushes out (spreads) the sea floor. This movement in the plates causes other plates (continental and oceanic) to move as well. This is how sea floor spreading causes continents to move.
About sea floor spreading?
Sea-floor spreading is what happens when the plates in the earth's crust move apart. During this movement of the plates, magma wells up from deep within the earth and fills in the cracks, forming a new oceanic crust, or sea-floor.
Who was the scientist who came up with the theory of the sea floor sprading?
The scientist who proposed the theory of sea floor spreading was Harry Hess, a geologist and Navy officer, in the early 1960s. He suggested that new oceanic crust is created at mid-ocean ridges and spreads outwards, pushing the continents apart. This idea later formed a key part of the theory of plate tectonics.
