intrusive igneous
When magma forces itself into surrounding underground rock, it is called intrusion or intrusive activity. This process can lead to the formation of igneous rock formations like dikes, sills, and plutons.
When magma forces itself across rock layers, it can create igneous intrusions such as dikes (vertical sheet-like intrusions) or sills (horizontal sheet-like intrusions). These intrusions form when magma solidifies as it cools, creating distinctive structures within the surrounding rock layers.
When a volcano collapses on itself a caldera is then formed.

I am learning about this in my Science class, and when a geologist looks at an extrusion, they know it's an extrusion because it is Igneous rock, and an extrusion helps tell the reletive ages of the layers around it.

A _____ is a city which rules itself and its surrounding territory.
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.

When the Earth was formed it was molten. The forces of gravity would make it shape itself into a sphere. This shape would be "frozen" in place as the Earth cooled and solidified.
