Best Answer

Shield volcanoes have fluid basaltic flows that are lower in silicates, making the lava very fluid without a tendency to form pyroclastics. Composite Cone volcanoes contain the highest percentage of silica content making the magma thicker with the greatest tendency to form pyroclastics and are the most dangerous volcanoes.

Shield Volcanoes: * Large base area * Gentle slope * Contains basic lava * Frequent eruptions * Quiet and gentle eruptions * Very tall in height due to large base area Composite Volcanoes: * Relatively small base area * Concave slope * Contains acidic lava * Violent eruptions * Repeated eruptions * Erupts from the side cones * Usually not very tall in height due to gentle slopes Acid-lava Volcanoes * Small base area * Steep slope * Contains acidic lava * Violent eruptions * Creates crater lakes (caldera) after eruptions * Tall in height due to steep slopes Cinder Cones * Small base area * Steep slopes * Symmetrical slopes * Moderate eruptions * Not tall in height as slopes are easily eroded
