11. 10. A sedimentary, igneous, or metamorphic rock can become an igneous rock by ___.
heating up so high it becomes molten material

12. 11. All of the different types of rock can become any other type of rock
True

13. 12. Sediments are substances such as sand, gravel, mud, clay, and fossils that are identified by
size of its fragments

14. 13. All igneous rocks originate from
magma or lava

15. 14. Why is granite coarse-grained?
It is intrusive, so minerals had longer time to grow and cooled slowly.

dead plants and animals.

18. 17. _______ are inorganic, which means it does not contain materials that were once alive.
Minerals

foliated

22. 21. Rock without layers is called.
nonfoliated

23. 22. A rock type can become sediments from the process of ________ and __________
