Across
  1. 4. a type of convergent boundary where the denser plate sinks under the less dense one and creates island arcs and underwater trenches
  2. 7. a type of plate boundary that moves apart. magma rises to fill the gap. creates rift valleys and mid-ocean ridges.
  3. 10. a type of boundary that slides horizontally. causes earthquakes
  4. 12. one plate dives beneath another & creates a volcano
  5. 13. the crust & upper part of the mantle
Down
  1. 1. a type of boundary that collides. creates mountains, intense earthquakes, etc.
  2. 2. a type of convergent boundary where an oceanic plate sinks under a continental plate, creating trenches and volcanic mountain ranges
  3. 3. the theory that suggests that Earth's lithosphere has plates that are split apart, and they interact with each other, causing global phenomenons
  4. 5. innermost layer of Earth. Made of metals.
  5. 6. the outermost layer of the Earth. Made of rock.
  6. 8. when this occurs to unstable isotopes,it gives energy to the internal Earth
  7. 9. second outermost layer of Earth. Made of rock, iron, and magnesium
  8. 11. the solid part of Earth that is made of rocks,minerals, soil, and sediment.
