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.

What material that rises to surface at mid-ocean ridge?

Magma rises to the surface at mid-ocean ridges due to the process of seafloor spreading. As two tectonic plates move apart, hot magma from the mantle wells up to fill the gap, creating new oceanic crust. This process is responsible for the formation of mid-ocean ridges and contributes to the Earth's continuous process of plate tectonics.


In the process of sea-floor spreading how does the ocean floor become wider?

As magma rises and solidifies at mid-ocean ridges, it creates new oceanic crust. This process pushes the older crust away from the ridge, causing the ocean floor to become wider. Over time, this continuous cycle of spreading and pushing apart results in the expansion of the seafloor.


How does sea floor spreading explain the movement of tectonic plates?

Sea floor spreading occurs at mid-ocean ridges where magma rises to create new oceanic crust. As the crust forms, it pushes the existing plates on either side away from the ridge, causing the plates to move. This process helps explain the movement of tectonic plates and how they interact with each other on Earth's surface.


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.


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.

How does sea floor spreading alter the shape of the ocean floor?

Sea floor spreading occurs when new oceanic crust is formed at mid-ocean ridges and pushes the existing crust apart. As the new crust cools and solidifies, it creates a symmetrical pattern where the ocean floor becomes wider. This process alters the shape of the ocean floor by creating a series of parallel ridges and valleys.
