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.

∙ 13y agoThe mid-ocean ridge is a continuous mountain range formed from the uplift of thin crustal rocks from rising magma due to decompression melting of mantle material at divergent plate boundaries.

In the process of sea-floor spreading how does the ocean floor become wider?
New floor forms and spreads from mid-ocean ridges
Which is associated with mid-ocean ridges?
Sea-Floor Spreading is associated with Mid-Ocean Ridges.
How do ocean ridges and deep-sea trenches support the theory of sea floor spreading?
Sea Floor spreading has to do with the crust forming at ocean ridges and being destroyed at deep sea trenches.
What material that rises to surface at mid-ocean ridge?
Sea-floor spreading due to convection currents in the Earth's mantle (although this is still under investigation). Magma is pushed up through the cracks in the sea-floor as the plates move apart.
Where are the youngest rocks found on the seafloor?
Near fault lines, it is there that rocks are created by the rubbing or colliding of the tectonic plates. Rocks could also be made by volcanoes via the cooling of magma and lava. The closer to the fault line you are the newer the rock and the farther away you get the older the rock becomes.
What is located in midocean ridges?
The Mid-Atlantic Ridge is found on the ocean floor in the middle of the Atlantic Ocean.
In the process of sea-floor spreading how does the ocean floor become wider?
New floor forms and spreads from mid-ocean ridges
Is a process by which ocean floors spread laterally from crests of main ocean ridges?
Sea floor spreading
What term describes the process that creates new oceanic crust at mid ocean ridges?
Sea Floor Spreading
What process helps explain how continents drifts?
Ocean-floor spreading.
What motion of the sea floor is responsible for the formation of the mid Atlantic ridges rift valley?
According to scientists, the process associated with seafloor spreading is responsible for the formation of the mid Atlantic ridges rift valley.
Where is new sea floor created?
the ridges
What happens at the ridges?
Sea floor spreading
Which is associated with mid-ocean ridges?
Sea-Floor Spreading is associated with Mid-Ocean Ridges.
What term describes the process that creates new oceanic crust at mid-ocean ridges?
Sea floor Spreading! -Lucy laboy Thanks that really helped alot.
What is ocean-floor spreading?
Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge. Seafloor spreading helps explain continental drift in the theory of plate tectonics.
The youngest rocks on the ocean floor are located where?
The youngest rocks on the ocean floor are located at mid-ocean ridges. These ridges are always found at divergent boundaries.
