  3. 6. Inside a magma chamber, this is responsible for pushing magma to the surface to create an eruption
  4. 8. the cause of plate movement: a circular motion and energy caused by the rising and cooling of magma in the asthenosphere
  5. 10. a boundary where plates collide into each other along which volcanoes often form
  6. 11. molten rock inside of a volcano
  7. 12. a plate boundary where plates slide past each other, usually not associated with volcano formation
Down
  1. 1. In a volcano, magma collects in a packet called a magma ___________
  2. 2. ____________ eruptions are eruptions out of the sides of a volcano
  3. 3. A smaller volcano with steeper sides
  4. 4. When an oceanic plate slides under a continental plate.
