Across 2. when one plate is converges and dives under the other 5. only half as fast as P waves; can't go through liquids or gases 7. lavea explodes into the air, rains down small cooled fragements that pile up 8. fastest type of earthquake wave; travels through all materials 12. formed at the spreading center 13. location of the surface directly above the earthquake source 14. parallel sliding plate boundary 16. igneous rock; extrusive; cooled so quickly that there are no grains 18. igneous rock; greenish black; dark colored; intrusive 21. dark colored mica 22. clear mineral; fizzes when HCl applied; you see double 23. igneous rock; salt and peppery; light colored; intrusive 24. when shale undergoes metamorphism it converts to this 25. lead sulfide mineral; blocky cleavage; metallic luster 26. clastic sedimentary; clay

Down 1. steep, tall, explosive type of volcano made of different layers of ash, lava, cinders, mud 3. sedimentary, clastic, has pebbles 4. deep depression in subduction zone 6. type of igneous rock that cools fast above ground , notallowing larger crystals to form 7. mechanism responsible for plate movement and earth magnetic field 9. olive green mineral containing a lot of iron and magnesium 10. foliated, looks like banded granite 11. "field mineral"; most common specific mineral in continental crust 15. igneous rock; extrusive; fine grained; light-colored 17. most common general category of mineral in crust; made of silicon and oxygen atoms with tetrahedral units 19. dark gray , igneous rock, fine grained; makes up most of oceanic crust 20. tall gently sloped volcanoe; lava very fluid; non-explosive

The look has changed! Some of the puzzles that people list for the public get indexed by the search engines (like Google). Some people find those puzzles and cannot figure out how to make a puzzle of their own. So this page now has the navigation sidebar.
