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.
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!! :)
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).
Did Alfred Wegener make sea floor spreading?
He is credited with coming up with the theory of continental drift.
What is seafloor spreading best described as?
sea floor spreading is were the earths crust is spreading under the ocean, going almost all the way around the earth, there are also volcanoes where the sea floor spreading, because of the magma coming up from the earth core
When did harry hess propose seafloor spreading?
1960 (although Hess' paper built upon Alfred Wegener's theory of continental drift , proposed in 1915).
Who proposed the theory of seafloor spreading based on maps of the ocean floor?
The Seafloor Spreading Theory was proposed by Harry Hess.
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.
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.
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.
