16. Rock Structures From Volcanic Activity & Movement of Magma

17. Batholith & Pluton
Large area of pooled magma that crystallizes to form intrusive igneous rock

18. Sill
A narrow band of magma that spreads out between rock layers that crystallizes to form intrusive igneous rock

19. Dike
A narrow band of magma that has cut through overlying rock layers – is vertical - that crystallizes to form intrusive igneous rock

20. Laccolith
Somewhat large area of pooled magma with a rounded top that crystallizes to form intrusive igneous rock
