What information indicates that new seafloor rock is forming the mid ocean ridge and then moving horizontally away from the ridge?
Mostly Volcanoes are located under ocean water.
How are magnetic patterns in sea floor rock evidence of seafloor spreading?
Magnetic alignment of rocks, in alternating strips that run parallel to ridges, indicates reversals in Earth's magnetic field and provides further evidence of seafloor spreading.
What is the theory of is an outgrowth of Alfred Wegener's theory of continental drift?
The problem with continental drift was no mechanism could be found by which the continents could drift through the solid rock of the ocean seafloor. In the 1950s the US Navy found the evidence of alternating polarity magnetic stripes on the ocean seafloor that were symmetrical on opposite sides of the midocean ridges. But this information was kept classified until the late 1970s. When it was declassified and made available to geophysicists it became the proof that showed the continents were not drifting as Wegener proposed, but the earth's crust was divided into plates that dragged the continents along with them as they moved.
Process that forms new seafloor?
Seafloor Spreading
What process forms new seafloor?
Seafloor spreading at midoceanic ridges.
What information indicates that new seafloor rock is forming the mid ocean ridge and then moving horizontally away from the ridge?
Mostly Volcanoes are located under ocean water.
What is the idea that continents have moved horizontally through the seafloor to their current locations?
seafloor spreading by Harry Hess
Idea that contineents have moved horizontally through the seafloor to their current locations?
the theory would be called Continental drift.
Satellites can obtain information about the seafloor because?
the sea surface level varies with seafloor depth

How did the wegener propose that the continents move horizontally?
Alfred Wegener proposed the theory of continental drift in 1912, suggesting that continents were once joined together in a single landmass called Pangaea. He suggested that the continents moved horizontally over time due to the process of continental drift, driven by forces such as seafloor spreading and mantle convection.
What seafloor is the process by which new crust is created when seafloor moves apart and magma rises?
Seafloor Spreading
Process that forms new seafloor?
Seafloor Spreading
How does the age of rocks in the seafloor provide evidence of seafloor spreading?
Rocks in the seafloor are moving one place to another
Seafloor is the process by which new crust is created when the seafloor moves apart and magma rises up?
seafloor spreading
What is seafloor plains?
large regions of the seafloor that appear flat but are not
