Caldera

13. Forms when magma hardents in a volcano’s pipe.
Volcanic neck

14. Magma that forces itself across rock layers that hardens.
dike

15. When magma squeezes between horizontal layers of rock.
sill

16. Forms when magma hardens underground to form igneous rock.
intrusion

17. A mass of rock formed when a large body of magma cools inside the crust.
Batholith

18. Landforms from lava and ash
Volcanic eruptions create landforms made of lava, ash, and other materials. These landforms include shield volcanoes, cinder cone volcanoes, composite volcanoes, and lava plateaus.
