    • A Shield volcano is characterized by gentle upper slopes and somewhat steeper lower slopes. Shield volcanoes are composed almost entirely of relatively thin lava flows built up over a central vent. They are formed by low viscosity basaltic magma that flows easily down slope away from the summit vent. Hence statement 1 is correct.
    • The low viscosity of the magma allows the lava to travel down slope on a gentle slope, but as it cools and its viscosity increases, its thickness builds up on the lower slopes giving a somewhat steeper lower slope. Most shield volcanoes have a roughly circular or oval shape in map view. Calderas are a common feature on shield volcanoes. Hence statement 2 is correct.
    • Very little pyroclastic material is found within a shield volcano, except near the eruptive vents, where small amounts of pyroclastic material accumulate as a result of fire fountaining events.
    • The best known shield volcanoes are the ones that make up the Hawaiian Islands, especially Mauna Loa and Mauna Kea. Hence statement 3 is correct.
