What is a sill dike batholith volcanic neck and lava plateau.?

A sill is an intrusion of magma that solidifies into a horizontal layer of igneous rock.





A dike is just like a sill except it cuts through layers vertically.





A batholith is a solidified magma reservoir under the surface.





A neck is the solidified inner core of a volcano - visible once the outer extrusive volcanic layers of lava flows have eroded away.





A lava plateau is a large region created by the extrusion of large volumes of lava to form a large flat region. These are also known as flood basalts.|||There's this thing called google....|||im with those two but def try google :o)|||a volcanic neck is the neck of the volcano(?), and a lava plateau, i'm assuming, would be the mouth of the volcano. where the lava comes out.
