Where does the salt in the ocean come from.
The process by which the ocean floor sinks beneath.
The scientist who created the seafloor spreading theory was hint.
The process of what continually adds new crust to the ocean floor along both sides of the mid ocean ridge.
The process by which the ocean floor sinks beneath a deep ocean trench and back into the mantle rift valley a deep valley that forms on land at a divergent boundary where two plates move apart.
Convection currents under the lithosphere push new crust that forms at the mid ocean ridge away from the ridge and toward a deep ocean trench.
Describe the process of sea floor spreading.
The process of adding more crust to the ocean floor.
Where there are trenches subduction takes place.
Ocean floor is made of which igneous rock.
Molten material rises from the mantle and erupts through the mid ocean ridge.
Most geologists think that the movement of earth s plates is caused by.
This is the result of the collision of two tectonic plates.
The process by which the ocean floor sinks beneath a deep ocean trench and back into the mantle is known as.
The process by which the ocean floor sinks beneath a deep ocean trench and back into the mantle.
The process by which ocean floor sinks beneath a deep ocean trench and back into the mantle is called subduction sub duk shun.
Subduction is the process by which the ocean floor sinks beneath a deep ocean trench and back into the mantle.
The process by which the ocean floor sinks beneath continental crust at a deep ocean trench and back into the mantle is known as.
Where there are deep ocean trenches a process called subduction takes place.
The process by which the ocean floor sinks beneath a deep ocean trench and back into the mantle is known as.
The ocean floor does not just keep spreading.
Subduction is the process by which the ocean floor sinks beneath a deep ocean trench and back into the mantle to be recycled.
This in turn results in the.
As subduction occurs crust closer to a mid ocean ridge moves away from the ridge and toward a deep ocean trench.
The process where the ocean floor sinks beneath the crust and back into the mantle is known as subduction.
Deep valley or underwater canyon where the oceanic crust sinks back toward the mantle.
Sea floor spreading and subduction work together.
