Igneous Rocks

5. The eight most abundant element and constitutes about 2% of the earths crust
9. extrusive equivalent of granite magma
13. chemical element of the alkali metal group and earth's crust is made up of it by 2.6%
14. intrusive igneous rock formed by the slow cooling underground of magma
17. Describes the temperature at which minerals crystallize when cooled
19. Any rock derived from magma that was poured out or ejected at earths surface
20. The appearance of the rock or how it feels
21. Formed by the cooling of solidification of molten
22. Magnesiun iron silicate with the chemical formula
24. hard natural igneous rock formation of visibly crystalline texture formed
25. rock formed from volcanic lava that cools rapidly at earth's surface

1. The process of the separation of two or more crystalline solids based on the difference in their soubilities
2. igneous rock showing a very coarse texture with large interlocking crystals
3. the primary aluminium-bearing mineral in mafic rocks formed at low pressure
4. A volcanic rock characterized by a rock being pitted with many cavities
6. transformation of some fraction of mass of a solid rock into a liquid
7. dense, coarse-grained,olivine-rich and an mafic intrusive rock
8. rock with large crystals are set in a finer-grained or glassy groundmass
10. Mineral that is found in many rocks
11. any group of important rock-foarming silicate mierals of variable composition
12. important to cement, ceramic, and glass industries
15. dark, heavy, and often altered and brecciated and contains diamonds in its rock matrix
16. rocks that formed from magma trapped within the earth
18. fined grained extrusive igneous rock formed when volcanic magma erupts outside of the volcano
23. Comes out of a volcano
