A section of the lithosphere that slowly moves over the asthenosphere, carrying pieces of continental and oceanic crust Plate Tectonics 2. The theory that sections of Earth’s lithosphere are constantly moving in slow motion Pangaea 3. The theory that all of the continents moved together millions of years ago, collided and created a “supercontinent” Subduction 4. When an oceanic plate sinks (or subducts) beneath another plate creating volcanoes or trenches Section 1: Convergent Boundary Divergent Boundary Pangaea Plate Plate Boundaries Plate Tectonics Subduction Transform Boundary Wegner Plate Boundaries 5. The cracks between the plates of the lithosphere Convergent Boundary 6. A plate boundary where two continental plates come together (or converge) and collide pushing the land upward creating mountains Wegner 7. The German scientist who proposed that the continents once moved together creating a “supercontinent” Divergent Boundary 8. A plate boundary where two oceanic plates move apart (or diverge) creating sea-floor spreading that allows lava or magma up through the cracks. OR when two continental plates move apart (or diverge) creating rift valleys Transform Boundary 9. A plate boundary where two plates slide past one another in opposite directions (or transform) creating earthquakes Name______________________________Teacher_________Class_________Date_____________ Section 2 – Earth’s Crust in Motion (pages 358-365) Earthquake 10. Shaking and trembling that results from the movement of rock beneath Earth’s surface Shearing directions 11. Stress that pushes a mass of rock in two opposite Fault 12. A break in the crust where slabs of crust slip past each other due to the build-up of stress Reverse Fault 13. A fault where compression forces cause the land blocks to move in opposite directions Strike-Slip Fault 14. A fault where shearing makes the rocks on either side of the fault sip past each other sideways with little up-or-down motion Tension 15. The stress force that pulls on the crust, stretching rock so that it becomes thinner in the middle Section 2: Anticline Compression Earthquake Fault Fault-block Mountain Fold Footwall Hanging Wall Normal Fault Plateau Reverse Fault Shearing Stress Strike-slip Fault Syncline Tension Fold crust 16. Bends in rock that form when compression shortens and thickens part of Earth’s Anticline 17. A fold in rock that bends upward into an arch Plateau 18. A large area of flat land elevated high above sea level Stress 19. A force that acts on rock to change its shape or volume Compression 20. The stress force that squeezes rock until it folds or breaks Normal Fault 21. A fault that is at an angle so one block of the rock lies above the fault while the other block lies below the fault Fault-Block Mountain 22. When normal faults uplift a block of rock Syncline 23. A fold in rock that bends downward in the middle to form a bowl Hanging Wall 24. The half of the fault that lies above the other half Footwall 25. The half of the fault that lies below the other half
