1. False. Intrusive rock has coarser crystal formation.
2. True. They are typically extrusive if formed by lava, intrusive through magma.
3. False. The process of lithification in sediments produces sedimentary rock.
4. True. This process compacts and cements the grains together, often squeezing out water in the process.
6. Metamorphic rock. Often rock near an igneous inclusion will metamorphose if the heat is not enough to cause melting.
7. False. All rocks in the rock cycle can become the other type with the right processes.
8. False. The rock cycle is continuous with rocks constantly shifting from one stage to another.
9. False. Foliation only occurs in metamorphic rock, with gneiss serving as a prime example.
