Across
- 3. the uppermost mantle, along with the overlying crust, that behaves as a strong layer
- 6. and thereby produce earthquakes, volcanoes, mountains, and the crust itself
- 8. the rock above the fault plane has moved down relative to the rock below
- 11. two plates grind past each other without harming the lithosphere
- 17. in which rocks are physically or chemically broken down by air, water, and living things
- 18. magma that reaches earth's surface
- 19. molten material that forms deep beneath earth's surface
- 20. any solid mass of mineral or mineral-like matter that occurs naturally as part of our planet
- 21. a sedimentary rock that goes under extreme pressure and heat
Down
- 1. destructive plate margins where the oceanic crust is being pushed down into the mantle
- 2. a reverse fault with a dip less than 45°, normally about 10-15°
- 4. a result in which the material above the fault plane moves up in relation to the material below
- 5. interactions among earth's water, air, and land that can cause rocks to change from one type to another
- 7. two plates move together
- 9. a theory that proposes earth's outer shell consists of individual plates that interact in various
- 10. process in which plate tectonics form a new oceanic lithosphere
- 11. a surface feature in the sea floor produced by a descending plate during subduction
- 12. weathered earth materials
- 13. two plates move apart
- 14. forms when magma cools and hardens underneath earth's surface or as a result from a volcanic eruption
- 15. a fault along which the movement is horizontal and and parallel to the trend of the fault
- 16. forms when sediment is eventually compacted and cemented
