Name: __________________________________ Date: ___________________ Period: _____________ Volcano Construction Lab 1. You will be constructing three Volcano Models as shown in your 22.6: Volcanoes notes. 2. You need two different colors of clay: one to represent cinders (outer part) & one to represent lava 3. Using your book, the volcano notes, and the information below, construct each type of volcano with the clay. Shield Volcano Made of Quiet Lava Large areas covered Base of 2o and summit of 10o Gently sloping dome Largest (by area covered) and flattest Cinder Cone Volcano: Loosely arranged Not very high Overall slope of 30-40o Made of cinders, ash, and dust Smallest and steepest Composite Volcanoes Made of alternate layers of cinders and lava Base of 5o and summit of 30o Tallest of all volcanoes (medium-sized base) Analysis Questions 1. Different types of volcanic eruptions form different types of volcanoes. Complete the chart below. Type of Eruption Quiet Explosive Type of Volcano (Shield, Cinder, Composite) Type of Plate Boundary (Divergent, convergent, hot spots, mid-ocean ridge?) Magma Type (Low or High Viscosity AND Low or High Silica) 2. Draw a diagram showing the similarities and differences between the three types of volcanoes. Cinder Cone Shield Composite/Strato-volcano 3. What is the general cause of volcanoes? 4. What is the ring of fire (pg. 693) AND what type of plate boundary causes the Ring of Fire? 5. Are the Ring of Fire volcanoes likely to be shield volcanoes or composite volcanoes? WHY? 6. What caused the Hawaiian Islands? Explain in detail!!
