Answer:
composite
Step-by-step explanation:
Composite volcanoes, also referred to as stratovolcanoes, is a type of volcano that has a conical shape and is composed of many hardened layers of lava, tephra, and volcanic ash. It is characterized by a high, steep shape and periodic explosive eruptions.
A characteristic feature of this type of eruption is powerful, often sudden explosions, accompanied by the release of a huge amount of tephra, forming pumice and ash streams. These eruptions are dangerous, as they occur suddenly, often without preliminary warning events.
