The **theory of plate tectonics** says Earth’s lithosphere is broken into plates that move on the mantle.<br /> <br /> 9. The **lithosphere** is Earth’s rigid outer shell (crust + upper mantle).<br /> <br /> 10. The **asthenosphere** is the soft, flowing layer beneath the lithosphere.<br /> <br /> 11. **Heat and convection currents** in the mantle cause material to move.<br /> <br /> 12. A **hypothesis becomes a theory** when supported by repeated evidence and observation.<br /> <br /> 13. **Plate tectonics** explains earthquakes, volcanoes, mountains, and sea-floor spreading.<br /> <br /> 14. **Evidence:** fossils, rock types, magnetic patterns, and satellite data.<br /> <br /> 15. At **mid-ocean ridges**, new crust forms as magma rises—called **sea-floor spreading**.<br /> <br /> 16. **Older crust** moves away from the ridge as **new crust** forms.<br /> <br /> 17. **Far edges** of the sea floor are forced under continents—**subduction**.<br /> <br /> 18. **Subduction:** one plate sinks beneath another into the mantle.<br /> <br /> 19. Earth’s **magnetic field** has reversed direction many times.<br /> <br /> 20. **Magnetic reversals** leave mirrored patterns in sea-floor rocks.<br /> <br /> 21. **Sea-floor dating** shows newer rock near ridges, older farther away—proving spreading.<br /> <br /> 22. **Earthquakes and volcanoes** occur where plates move—evidence of active spreading.<br /> <br /> 23. The **map** showed matching patterns across oceans, proving continents move.<br /> <br /> 24. Developed from **Wegener’s drift idea** → **sea-floor spreading** → full **plate tectonics theory**.<br /> <br /> 25. **Causes:** mantle convection, ridge push, and slab pull.<br /> <br /> 26. **Convection current:** flow of heated, less dense material rising and cooler material sinking.<br /> <br /> 27. **Lower velocity waves** show hotter, softer regions in the mantle.<br /> <br /> 28. **Higher velocity waves** show cooler, denser rock.<br /> <br /> 29. **Mantle plumes** form from hot material rising from deep within the mantle.<br /> <br /> 30. **Ridge push:** gravity slides new crust away from mid-ocean ridges.<br /> <br /> 31. Helps **predict earthquakes, locate resources**, and understand natural hazards.<br /> <br /> 32. Guides **safe construction**, avoiding fault lines or volcanic zones.<br /> <br /> 33. **Wegener’s evidence:** fit of continents, fossils, rock layers, and climate clues.<br /> <br /> 34. **Continental drift** describes movement; **plate tectonics** explains the mechanism.<br /> <br /> 35. **Oldest sea-floor** is near the **edges** of the Atlantic, farthest from the ridge.<br /> <br /> 36. The **mid-ocean ridge** is where the youngest rocks are and magnetic stripes mirror outward.
