Plate Tectonic/Rock Cycle Crossward Puzzle

5. a sedimentary rock that goes under extreme pressure and heat
7. any solid mass of mineral or mineral-like matter that occurs naturally as part of our planet
13. two plates grind past each other without harming the lithosphere
14. magma that reaches earth's surface
15. a result in which the material above the fault plane moves up in relation to the material below
17. a theory that proposes earth's outer shell consists of individual plates that interact in various
18. forms when magma cools and hardens underneath earth's surface or as a result from a volcanic eruption
19. molten material that forms deep beneath earth's surface
20. interactions among earth's water, air, and land that can cause rocks to change from one type to another
21. a reverse fault with a dip less than 45°, normally about 10-15°

1. destructive plate margins where the oceanic crust is being pushed down into the mantle
2. two plates move together
3. forms when sediment is eventually compacted and cemented
4. two plates move apart
6. a fault along which the movement is horizontal and and parallel to the trend of the fault
8. process in which plate tectonics form a new oceanic lithosphere
9. weathered earth materials
10. the uppermost mantle, along with the overlying crust, that behaves as a strong layer
11. and thereby produce earthquakes, volcanoes, mountains, and the crust itself
12. in which rocks are physically or chemically broken down by air, water, and living things
13. a surface feature in the sea floor produced by a descending plate during subduction
16. the rock above the fault plane has moved down relative to the rock below
