What is the difference between subduction and seafloor spreading?
Wiki User
∙ 13y ago
Sea floor spreading is where new oceanic crust is formed through volcanic activity and then moves away from the ridge. Subduction is when one tectonic plate moves under another tectonic plate.
Hope this helped :)

∙ 7y agoHarry Hess was an American geologist who studied sea-floor spreading. Alfred Wegener was a German scientist who studied continental drift. Sea-floor spreading made mid-ocean ridges and continents drift apart. Because of Hess's observation, many scientists began to have second thoughts about rejecting Wegener's hypothesis.

∙ 13y agosea floor spreading is evidence for continental drift?

∙ 13y agothe continental drift theory is the theory when a scientist thought that all the continents fit together like puzzle pieces. the were evidence to back it up though

∙ 12y agoits not really different because sea floor spreading causes continental drift

What is the difference between spreading and subduction?
spreading: rock rises upward then spreads outward.subduction: rock moves inward then subducts downward under lighter rock.
What is the difference between a transform fault and the subduction zone?
Ask Google ?
Give two pieces of evidence for seafloor spreading?
Geographic similarities between continental margins on both sides of the Atlantic Ocean and similarity of strata and fossils found on those margins.
What happens along a divergent boundary between two oceanic plates?
A rift valley, volcano, earthquake, trench.
What are the difference between trenches and faults?
A fault is a crack from stress within the Earth. A trench is formed by subduction zones and is usually deeper and wider.
Explain the relationship between trenches and seafloor spreading?
1. New sea-floor is created by the upwelling of magma at mid-ocean spreading centers; old ocean floor is destroyed by subduction at deep sea trenches. 2. The area is a subduction zone. Magma from underground comes up and destroys that crust. That crust is then recycled and the magma cools and hardens. That creates new land, that creates the trenches. Seafloor spreading is in the ocean and happens with convection currents. That is the relationship between. 3. As new seafloor is formed at mid-ocean ridges, the old seafloor is pushed down into trenches at subduction zones.

What Is the mechanism responsible for producing the new seafloor between two diverging plates?
Sea Floor spreading
What is the mechanism responisble for producing the new oceanic crust between 2 diverging plates?
Seafloor Spreading.
How do you explain the process of the seafloor spreading?
The seafloor spreading definition is the geologic process that occurs at the boundary between 2 plates where molten material within the earth pushes its way up, causing the plates to move away from each other. At these divergent boundaries molten material cools and hardens, creating new oceanic crust or seafloor

Place where seafloor spreading occurs?
Seafloor spreading occurs at the boundary between two tectonic plates. As the plates divide, magma comes up through the crack and cools to form new sea floor. The farther away the floor is from the boundary, the older it is.
What could wegener not satisfactorily explain about continental drift?
No
What is the difference between subduction zone and a continent continent collision zone?

What is the relationship between platetectonics and seafloor spreading?
Plate tectonics is the theory that earth is made of plates that move slowly. Sea floor spreading is related to this because the split created in the sea floor is created by the plates moving apart.

Geographic similarities between continental margins on both sides of the Atlantic Ocean and similarity of strata and fossils found on those margins.
