1. CHAPTER 5 VOLCANOES AND VOLCANIC HAZARDS READING QUIZ #3 – 5 QUESTIONS

2. 5.9 1. Explain why volcanic ash is a hazard for aircraft.

3. 5.8 2. How do large volcanic eruptions affect climate?

4. 5.8 3. _____________ are large steep-sided depressions with diameters that exceed 1 kilometer.

5. 5.9 4. ___________ eruptions usually emit fluid basaltic lava from a fracture in the crust that can blanket large areas and create basalt plateaus (a.k.a. flood basalts).

6. 4.2 5. When a volcano becomes inactive, congealed magma often solidifies in the conduit (pipe). After erosion weathers away the volcano, the very hard and weathering-resistant structure left standing is referred to as a volcanic ______.
