Here are the matches for the Plate Tectonics terms and their corresponding descriptions:

  1. Convection Currents - The rise of hot less dense magma and the fall of cooler, more dense magma in the asthenosphere creates this process.
  2. Biogeographical Evidence - Animal Fossils that were found on several different continents that could not have swum the ocean to get there.
  3. Paleoecology - Tropical Plant fossil found in Antarctica that suggests the climate of Antarctica has changed from tropical to arctic!
  4. Seafloor Spreading - The name of the process that creates new ocean crust at the Mid-Ocean Ridge.
  5. Cratons - Stable interior portions of continental crust (these are what lined up to link South America to Africa).
  6. Continental Drift - Wegener's unsupported theory that the continents were all one big landmass, and then moved apart to present day.
  7. Volcanic Eruptions - Explosive volcanic eruptions that produced dangerous amounts of lava, gas, and ash.
  8. Pangaea - The name of the supercontinent.
  9. Convergent Boundary - Plate boundary that collides together.
  10. Divergent Boundary - Plate boundary that separates.
  11. Transform Boundary - Conservative Plate boundary that doesn't create landforms, but just slides past each other.
  12. Volcanic Arc - The area around the Pacific Ocean is called the Ring of Fire because oceanic crust converges with continental crust and creates one big ___________________ (string of coastal volcanoes).
  13. Island Arc - Two oceanic plates collide, resulting in this string of volcanoes out in the middle of the ocean.
  14. Topography - A vocab word that means "shape of the land" and describes different landforms and features.
  15. Focus - Point underground where an Earthquake originates.
  16. Epicenter - Point on the surface, directly above where the earthquake originated. This is where the magnitude is felt the most.
  17. Plate Tectonics Theory - Theory that explains why the Continents have moved: Convection in the asthenosphere has moved the plates in the lithosphere.
  18. Subduction - In a convergent boundary between two crusts of different densities, the more dense crust will sink down. This is called_____________.
  19. Trench - When oceanic crusts subduct under another crust, this DEEP landform in the ocean is created. If you flew above it, it would be a dark line in the water.
  20. Mid-Atlantic Ridge - Geologist and Naval officer Harry Hess discovered the longest underwater mountain range when he was looking for enemy submarines during World War II. He named it the _________________________.
  21. Fault Line - A plate boundary that results in Earthquakes is called a _________________ (San Andreas has a famous one...).
  22. Hot Spot - Hawaii was made from one of these, where magma plumes upward through the middle of a plate, instead of seeping out at a plate boundary.
  23. Paleomagnetism - A study of ocean floor rocks, and how the iron and nickel alignment suggest the Earth's poles have reversed several times.
  24. Mountain Range - Convergent boundary of two continental crusts (with similar density) uplift to form this landform. Ex: Himalayas and Appalachians!
  25. Magma - Equation for a Volcano = pressure + crack in the crust+ this molten material ___________ as it exits the crust.
