- The volcano that classify that have no recorded eruption but erupted for the last 10,000 years is called dormant volcano. Dormant volcano is an active volcano that is not erupting, but supposed to erupt again.
- The lava that creates shield volcanoes is fluid and flows easily. The spreading lava creates the shield shape.
- Composite is a most like mountain volcano.
- Phreatomagmatic eruption is resulting from the interaction of new magma or lava with water and can be very explosive.
