What else can I help you with?
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 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.
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.
The seafloor spreading hypothesis indicates what as the primary cause of continental movement?
The seafloor spreading hypothesis suggests that the primary cause of continental movement is the upwelling of magma at mid-ocean ridges, which creates new oceanic crust. The movement of this newly-formed crust pushes the existing seafloor apart, leading to the gradual separation and movement of the continents.
What did the magnetic strips prove in seafloor spreading?
They proved that the seafloor was spreading.
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?
they use sensors to measure the shallow depths of the ocean and can detect variations in sea surface height caused by the gravitational pull of the seafloor's features. This data is then used to create maps of the seafloor topography and to study ocean currents, tides, and marine habitats.
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
What is a sensitive device used to detect magnetic fields on the seafloor?
A magnetometer is a sensitive device used to detect magnetic fields on the seafloor. It measures the strength and direction of magnetic fields, which can provide valuable information about the geological structure of the seafloor and help in identifying magnetic anomalies caused by different rock types or mineral deposits.
What is seafloor plains?
large regions of the seafloor that appear flat but are not
What did the magnetic strips prove in seafloor spreading?
They proved that the seafloor was spreading.
