D. all of these
6. What are the flat layers that form as rocks are squeezed called?
A. foliation
7. Sediments come together by these processes to create sedimentary rocks.
A. compaction and cementation

D. atmospheric pressure
9. When sediments are buried the weight above them can make them into __________ rocks. When they are buried by more weight they can become __________ rocks.
im not sure
11. For an igneous rock to become a metamorphic rock it must
C. change composition or mineral shape by heat or pressure
True 14. Precipitates are the solid materials left behind after a liquid evaporates.
True 15. As magma cools, different crystals form in the process known as metamorphism.
False 16. When a rock melts completely it can become the metamorphic rock migmatite.
True 17. The rock cycle describes the transformation of one type of rock to another.
False 18. When sediments become sedimentary rock they often have changes in composition.
True 19. The White House is made of pink sandstone that was painted white.
True 20. Fossils are the remains of once-living organisms.
21. Intrusive igneous rocks solidify beneath the surface.
22.. Slow cooling allows time for large crystals to form.
23. Sediments are laid down, or Compacted, before they can be formed into sedimentary rocks.
24. Fluids that crystallize in the spaces between the loose particles of sediments create rock by Cementation.
25. Regional metamorphism changes enormous quantities of rock over a wide area.
26. Contact metamorphism changes a rock that is in contact with magma because of the extreme heat.
27. In a metamorphic, minerals separate by Bedding into lighter and darker bands.
28. The rocks that form from an erupting volcano are Extrusive Igneous rocks.
29. Cemented sediments become Clastic sedimentary rocks.
30. Lithification occurs when sediments are squeezed together by the weight of overlying sediments on top of them.
