Across
- 2. the innermost layer of the earth, generates a magnetic field
- 4. when the crust slips and causes the earth to shake violently
- 6. the circular motion of hot molten rock rising then cooling and sinking beneath the crust
- 8. when the more dense plate pulls itself into the mantle at a subduction zone
- 12. a large area of crust that floats on the mantle
- 13. when two plates slide past each other, causing fault lines and major earthquakes
Down
- 1. when two plates crash into each other, likely causing mountains to form
- 3. when two plates move away from each other, causing a rift valley
- 5. this occurs when an opening in the seafloor builds islands as the plates move over it, like Hawaii
- 7. generated by earth's core, it is what makes compasses work and protects the earth from the Sun's radiation
- 9. an opening in the crust that spews magma (now called lava) out of the top and along the sides
- 10. what we live on, the outermost layer of the earth, the rock that floats on the mantle
- 11. when the more dense plate slides under the less dense plate
