divergent
The magma flows upward from the split in the crust caused by the boundary.
Mount Etna Was Formed By Destructive Plate Boundaries. This Is When One Crust Is Forced Under Another Crust. It Stands At The Convergent Boundary Where The African Crust Is Being Sub Ducted Beneath The Eurasian Crust. This Causes The Latter To Deform And Forces the Magma Up Into Weak Spots In The Earths Crust (mount Etna) When There Has Become To Much Of A Magma Build Up In The Mantle.
The opening in the earth crust which magma rise to the surface are Volcanoes
Ocean crust is formed by intrusive magma at mid-ocean-ridges. The magma cools and solidifies into peridotite, basalt, or gabbro.
A divergent plate movement occurs when two plates move away from each other. Magma from the mantle underneath the crust to rise up the surface to cool and solidify at the plate boundary. This divergent boundary is considered constructive since new crust is formed. Divergent takes place at the boundary of the oceanic plates and forms new sea floor. This process is called sea-floor spreading. As magma rises up to the surface, it piles up and solidifies, slowly forming a long chain of mountains on the ocean floor, called an oceanic ridge.

If the magma cools on the surface of the crust, it is called extrusive igneous rock
When a huge piece of crust diverges (pulls apart), the crust becomes fractured and magma spills out on the surface.
Crust is being made there, from the upwelling of magma.
Volcanoes bring liquid rock (magma) to the surface, which may have heavier elements from the lower crust and mantle.
The rock that formed from lava would have smaller crystals than the rock that formed from magma.
All igneous rock is formed from solidified magma or lava.
No. Granite is an intrusive igneous rock, formed from the cooling, solidification, and crystalization of magma below the earth's crust/surface.
