What is a volcano? What are the different types of volcanic eruption? * Quiet Eruptions * Explosive Eruptions Describe the different types of volcanic eruptions. * Quiet Eruptions- explodes with much less suddenness. Lava does not cool and harden. Lava that creates a quiet volcano is still runny and flowing. Pockets of hot gas form that squirt fountains of lava into the air. Lava later on becomes basalt. * Explosive Eruptions- erupts suddenly with a terrifying force. This forms when magma has cooled to make a lava plug blocking a crater. When the plug traps hot gas and magma under the ground, and the hot gas builds up until the pressure becomes too great, hot gas and magma explodes out of the volcano in a shower of dust, shes, cinder, and volcanic bombs.
 * A volcano is an opening in a planet's surface which allows hot magma, volcanic ash and gas to escape from below the surface.
