Seafloor is the process by which new crust is created when the seafloor moves apart and magma rises up?
seafloor spreading
What is the process by which new crust is created when the seafloor moves apart and magma rises up?
Seafloor Spreading
How did Harry Hess discover seafloor spreading?
Harry hess' hypothesis was hot/less dense material rises up the Earth's crust toward the mid-ocean ridges. When the seafloor breaks apart, magma is forced upward and through the cracks. It cools, and becomes a new seafloor. When it moves away from the mid-ocean ridge, it becomes denser and sinks. This helps form ridges.
What does seafloor spreading create?
New oceanic crust is created at the mid-ocean ridges.
Does seafloor spreading cause the earth's crust to expand?
New oceanic crust is being created at seafloor spreading zones, and crust is alternately being subducted and destroyed at subduction zones.
What is the process in which new sea floor forms as older sea floor is pulled apart?
Seafloor Spreading created by harry hess

What seafloor is the process by which new crust is created when the seafloor moves apart and magma rises up?
plate tectonics
What is the place that new seafloor is created?
in mid ocean ridges
What is Harry Hammond Hess famous for?
Harry Hammond Hess (1906-1969) developed theories of plate tectonics, particularly seafloor spreading as the source of new oceanic crust.
How did harry hess's hypothsis explain seafloor movement?
It explained seafloor movement because he researched that hot/less dense material rises to Earths crust, at the Mid-Atlantic Ridge. At the hole the magma cools making new seafloor. He also found out that there were new rocks near the Mid-Atlantic Ridge and old ones farther away. Hess also theorized that this seafloor has to filter somewhere- this somewhere is called the subduction zone. The subduction zone is an area where old seafloor sinks and the plates melt it forms into magma, building pressure within the Earth. When there is too much pressure the Earth lets out this energy in Arcs, Volcanic islands, etc.
How did the new evidence support Hess's theory of seafloor spreading?
Umm Maybe by the way sea floor spreads apart along both sieds of a mid ocean ridge as new crust is added
