Extrusive igneous rock-
Sometimes lava erupts and flows from long cracks in the earths crust called fissures. Lava flows from fissures on the ocean floor at places where tension is causing the ocean to be pulled apart. This lava cools to form new ocean floor.
Hope it helps.

∙ 9y agoThere are divergent boundaries where the plates are moving away from each other, causing magma to rise up. The boiling lava is almost immediately cooled and forms new sea floor crust.

Seafloor Spreading created by harry hess
In the process of sea-floor spreading how does the ocean floor become wider?
New floor forms and spreads from mid-ocean ridges
New crust forms on the ocean floor due to what process?
Plate tectonics.
Which geologic process forms new crust on the ocean floor?
seafloor speading
What is the process that adds new material to the ocean floor?
Sedimentation.
What is the process that continually add new material to the ocean floor .?
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.
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.
