Where is sea floor crust created?
It was created on the sea floor.
Portion of the earth's crust that lies beneath the ocean floor?
The portion of Earth's crust that lies beneath the ocean floor is called oceanic crust. It is thinner and denser than continental crust, primarily composed of basaltic rocks, and formed at mid-ocean ridges through volcanic activity.
The ocean bottom is part of the crust?
sea floor
The process by which molten material adds new oceanic crust to the ocean floor?

What process adds new crust to the ocean floor?
Volcanic eruptions are one process that adds new material to crust. Lava from the volcanoes eventually cool, forming new land. Sea floor spreading also adds new material to the crust.
What is a good sentence for sea floor spreading?
Sea floor spreading mean the process by which molten material adds new oceanic crust to the ocean floor
How do ocean ridges and deep-sea trenches support the theory of sea floor spreading?
Ocean ridges and deep-sea trenches support the theory of sea floor spreading through the process of plate tectonics. At ocean ridges, new oceanic crust is formed as magma rises and solidifies, pushing the existing crust apart. Deep-sea trenches are areas where old oceanic crust is being subducted back into the mantle, completing the cycle of sea floor spreading. This continuous movement of crust at ridges and trenches provides evidence for the theory of sea floor spreading and the movement of tectonic plates.
What is the process new crust formation called?
sea-floor spreading
How many is the Earth's crust divided into?
Sea floor spreading theory
What are magnetic strips on the sea floor caused by?
Movement of the ocean crust
Which layers of the earth are involved in sea-floor spreading?
Oceanic crust
How does sea floor spreading make the continents move?
Under the oceanic crust is the layer of the earth called the mantle. This layer is moving rock that is very, very hot! As the hot material in the mantle pushes up through the crust in the sea floor, it cools and becomes new crust as it pushes out (spreads) the sea floor. This movement in the plates causes other plates (continental and oceanic) to move as well. This is how sea floor spreading causes continents to move.
