The slab of volcanic rock that is formed when magma forces itself across rock layers is called a dike. This will eventually build into mountains.

there are many parts of a volcano. There is the magma chamber: where all of the magma is held. There is the pipe: where the magma comes up and through the volcano. There is the dike, where where a slab forms when magma forces itself across rock layers. There is the crater, where a bowl shaped area forms around a volcanoes central vent. There is the vent: where magms comes out.

Maybe but not true.
The slab that forms when magma forces itself across rock layers is called a dike.
If the magma forces itself along a plane that is parallel to the bedding or foliation planes of the rock strata then (in other words it squeezes between two existing layers) it is a sill. If however it cuts across the bedding or foliation planes it is a dyke. For more information, please see the related links.
Magma fills the gap between plates at DIVERGENT boundaries.

A body of magma that cuts through (and across) adjacent rock. Similar to a secondary vent but it does not strike through the surface. It then hardens and forms rock. It is always younger than the rocks which surround it.
A crosscutting feature is always younger than the rock layers it cuts through because the feature always forms after the rock layers have been formed, making the rock layers older.
Light itself, the way it plays across forms like architecture and landscape.
