Across
  1. 4. formed from ‘more liquid-y’ lava that flows further away from the eruption before it hardens; because of this, it has sides with a shallow, broad profile - you know, kinda like a shield
  2. 5. -true or false- the sciences are by far the most interesting subjects you get to study in school
  3. 8. process of one plate being smooshed up under another plate, and results in the oceanic crust of the bottom plate being recycled back down into the earth’s mantle
  4. 10. theory explaining how lithospheric plates move around and smoosh into/under/away from each other and form the geologic features we see (such as mountains, sea trenches, volcanoes, continents and oceans)
  5. 11. plate boundary where two plates are moving against each other
  6. 14. this type of crust exists over the entire planet, including under continents, but we mainly think of it as the type of crust underneath oceans
  7. 17. plate boundary where two plates are smooshing up against each other (i.e., the plates are converging)
  8. 18. often formed at convergent boundaries where both plates have continental crust, and the two converging portions of continental crust push up against each other
Down
  1. 1. a cone shaped volcano made up of layers of hardened lava, and the most common type of volcano
  2. 2. plate boundary where two plates are moving away from each other (i.e., the plates are diverging)
  3. 3. caused by the sudden release of energy in the earth’s crust, and occur most frequently at plate boundaries
  4. 6. occurs at divergent plate boundaries; results in an oceanic ridge where new oceanic crust is formed
  5. 7. kind of like the opposite of an oceanic ridge (or ‘mid-ocean ridge’), it forms at convergent plate boundaries where oceanic crust is subducted back down into the mantle
  6. 9. formed at weak spots in the earth’s crust, where magma is pushed up and out onto the earth’s surface
  7. 12. outermost layer of the earth’s crust, it forms the continents and continental shelves and is less dense than oceanic crust
  8. 13. dome shaped structure that builds up because thick lava flows out slow and hardens relatively quickly after it emerges, they are particularly common at convergent plate boundaries
  9. 15. -true or false- the earth’s crust has varying thickness, ranging from approximately 10 km thick on the ocean floor, up to 70 km thick at Mount Everest
  10. 16. a break or crack in the earth’s crust, often formed due to two plates smooshing against each other
