Magma
Yes, when magma rises from an ocean ridge, it can produce new material through a process called seafloor spreading. As the magma reaches the surface, it cools and solidifies, forming new oceanic crust. This process contributes to the continuous expansion of the seafloor and the formation of new crustal material.
it is a REEF
When spreading molten material rises from the mantle in the sea-floor and erupts, it can create sea mounts, which are underwater mountains. If enough material is ejected, the mounts will break through the surface of the water to create islands.
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.
The sea-floor spreading begins at the mid-ocean ridge, which forms along a crack in the oceanic crust. Along the ridge, molten material that forms several kilometers beneath the surface, rises and erupts. At the same time, older rock moves outward on both sides of the ridge. As the molten material cools, it forms a strip of solid rock in the center of the ridge. When more molten material flows into the crack, it forms a new strip of rock.
Less/dence material rises
Melted material that rises from the mantle is called magma. Once magma reaches the Earth's surface, it is then referred to as lava.

An underwater ridge rising close to the surface is called a reef. A reef is typically made of rock, sand or coral that lies 80 meters or less beneath low water.
it is called the art of materilintasion which was discovered by the neanderthals
The Mid-Ocean Ridge Is From The Mantle.
it erupts from the mantle witch is part of the structure of the earth.
