Here's why:
* Explosive eruptions: Stratovolcanoes are formed by eruptions that are typically explosive, releasing ash, gas, and pyroclastic flows.
* Layers of material: The erupted material (lava, ash, and rock fragments) cools and solidifies, creating layers that build up over time.
* Conical shape: These layers create the distinctive cone-shaped structure of a stratovolcano.
Some famous examples of stratovolcanoes include Mount Fuji in Japan, Mount Vesuvius in Italy, and Mount Rainier in the United States.
