Concept Bank
1. High level area formed by repeated lava flows
2. Formed by lava flows alternating with explosive eruptions.
3. Cone-shaped mountain formed from ash, cinders, and bombs
4. Hole left by collapse of volcanic mountain
5. Gently sloping mountain formed by repeated lava flows.
6. Result from quiet eruptions.
7. Very steep mountains.
8. Form from many thin layers of lava.
9. Massive rock when large body of magma cools inside crust.
10. Magma hardens in pipe and then volcano erodes away.
11. Forced between rock layers.
12. Forced through (across) rock layers.
13. Magma forces rock to bend up; when rock erodes, a dome is left.
