  1. 1. a hard, sedimentary cryptocrystalline form of the mineral quartz, categorized as a variety of chert.
  2. 3. is more porous and its density, metamorphic rock, higher temperatures and pressures, It is formed by the metamorphosis of granite, or sedimentary rock.
  3. 6. rock and mineral fragment that are loose in water
  4. 7. a sedimentary rock Most limestone's form in shallow, calm, warm marine waters
  5. 11. igneous rock, associated with mountain ranges
  6. 12. they can change into new rocks without erosion or melting
  7. 14. the individual particles in a rock
  8. 15. a mafic intrusive igneous rock composed largely of the calcium-rich plagioclase labradorite, orthopyroxene, and olivine.
  9. 17. sedimentary rock composed of mud that is a mix of flakes of clay minerals
  10. 18. rock that erupts onto earths surface
Down
  1. 2. most abundant rocks in earth,most form deep below earths surface, and some on earths surface]
  2. 4. sedimentary rock composed mainly of sand-sized mineral particles or rock fragments.
  3. 5. a naturally occurring volcanic glass formed as an extrusive igneous rock. It is produced when felsic lava extruded from a volcano cools rapidly with minimal crystal growth.
  4. 8. an intrusive igneous rock composed principally of the silicate minerals plagioclase feldspar, biotite, hornblende, and/or pyroxene.
  5. 9. a mafic extrusive igneous rock formed from the rapid cooling of magnesium-rich and iron-rich lava More than 90% of all volcanic rock on Earth is made of this.
  6. 10. naturally occurring solid mixture composed of minerals, smaller rock fragments, organic matter, or glass
  7. 13. a metamorphic rock composed of recrystallized carbonate minerals
  8. 16. molten rock when it is inside the earth
  9. 17. a fine-grained,metamorphic rock comes from an original shale-type sedimentary rock
