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.
magma mixing
magma and volcanic mountains
Extruded magma (lava) can cool on the surface, or under water. Magma also cools underground, forming intrusive igneous rocks such as granite.
Melting is the process in the rock cycle that causes magma to form.
contact metamorphism
the rock will melt down slowly then blow
from being under the mantle the gas pressure builds up and forces magma out forming a hot spot.
Contact metamorphism is the process of forming rocks from the heat of magma intrusion. Regional metamorphism, meanwhile, is the process of forming rocks by pressure and heat at plate boundaries.

magma
Magma that forces its way into rocks and hardens is called intrusion.
magma mixing
Interior pressure of the forces the magma through the crack. This upwelling of magma then rapidly cools and becomes brittle as it hardens. The pressure of the subsurface magma then breaks this brittle rock and forces more magma up in a continuous cycle.
No, when magma forces itself BETWEEN rock layers it is called a sill. When the magma cuts THROUGH rock layers it is called a dike.
