Answer:
1. Explosive eruption- is a volcano eruption of the most violent type.
Such eruptions result when sufficient gas has dissolve under pressure
within a discussion magma such that expelled lava violated froths into volcanic ash when pressure is suddenly lowered at the vent.
Magma has greater amount of dissolve gas.
2. Violent eruption- has low-silica content magma & high viscosity
magmas. The explosive bursting of bubbles fragments that magma
into clots of liquid that cool as they fall to the air. These solid
particles become pyroclasts or volcanic ash.
Magma has low silica content.
3. Silent eruptions- volcanous that are very hot , low silica magma generally errupt quietly. In a silent eruption, lava erupts in a stream
of low- viscosity lava, called a lava flow. Lava flows from a silent
eruption can travel for great distances.
Magma has high temperature.
