10. What are the steps to becoming a sedimentary rock?

Answers:
1. D
2. A clastic sedimentary rock is made up of solid sediments, and a bioclastic rock is
made of living organisms or materials from organisms.
3. The mineral composition of vesicular andesite is plagioclase feldspar, biotite,
amphibole, pyroxene, and quartz.
4. Garnet is made up of iron, aluminum, silicon, and oxygen. The number of
chemicals that make it up is 20.
5. The two types of metamorphism are regional and contact. Contact is when older
rocks come in contact with magma of an intrusion or extrusion, and regional is
when an increase in temperature and pressure transforms older rocks to a series of
metamorphic rocks.
6. C
7. Melting and solidification.
8. D
9. Plagioclase feldspar.
10. Deposition, Burial, Compaction and/or Cementation.
