usually from lava sinking to ocean floor and cooling.

∙ 9y agoNew rock is added to the ocean floor by the process of seafloor spreading, in which the magma is pushed out of the mantle, and is cooled by the water. Creating a new layer of hard rock.

Hardens to form new rock at mid-ocean ridges?
Sea- Floor Spreading molten material erupts through the valley that runs along the center of some mid-ocean ridges. This material hardens to form the rock of the ocean floor. Mid-ocean ridges an undersea mountain chain where new ocean floor is produced.
Location in ocean basin where new ocean floor is formed?
This sounds like the mid ocean ridge. This is where the plates are moving apart and magma wells up to form new rock.
In the process of sea-floor spreading how does the ocean floor become wider?
New floor forms and spreads from mid-ocean ridges
Explain the process by which new sea floor forms at mid-ocean ridges?
as it spread away from a mid-ocean ridge, the sea floor carries with it a record or magnetic reversals. i hope this answer would be correct :) also, when the magma rises through fractures in the sea floor at the mid-ocean ridge, the magma cools and forms new rocks. this new rock takes place of the old rock and the old rock gets pulled away.
When new rock is added to an oceanic ridge the magnetized strips on side of the ridge are evidence of sea floor spreading this is because the rock the two sides of the ridge?
are equal in width and polarity
What is part of molten rock at mid-ocean ridges?
Molten rock at mid-ocean ridges is the result of sea-floor spreading. WRONG

What is the process that creates new ocean crust to form molten rock?

What happens when sea-floor speading occurs?
the process by which new material is added to the ocean floor along the boundary between diverging plates.
What are the youngest rocks on the ocean floor?
those located at the fault in the bottom of the ocean because it is a volcano and produces new rock everytime the lava cools.
When lava flows from fissures on the ocean floor at places where tension is causing the ocean floor to be pulled apart new is?
Ocean floor
What type of boundary occurs in the new ocean floor?
New ocean floor is created at mic-ocean ridges which are divergent plate boundaries.
The process that continually adds new material to ocean floor is?
sedimentation
How does new ocean floor form?
Sea Floor Spreading!
What cause new material to form at a mid ocean ridge on the ocean floor?
New material forms on the ocean floor of the mid-ocean ridge due to plate tectonics and volcanic activity. Volcanic eruptions deposit cooled magma on the ocean floor.
