1. Volcanoes Shield Volcanoes Stratovolcanoes Cinder Cones

2. Shield Volcanoes (e.g. Mauna Loa)  Huge structures, in both volume and height  Built of very fluid basaltic lavas --> gently sloping sides

3. Hawaiian lava flows  Pahoehoe flows - smooth, ropy surface  Aa flows - rough, jagged surface

4. Stratovolcanoes (e.g. Mt. Shasta)  Large volcanoes, particularly in height  Built of more viscous lava flows and pyroclastic debris --> steeper slopes

5. South Sister, Oregon Cascades

6. Lava Bomb - South Sister, Oregon Cascades

7. Mount Rainier, Washington

8. Cinder Cones (e.g. Wizard Island)  Relatively small volcanoes  Built primarily of pyroclastic debris --> steepest slopes (at angle of repose)
