Here's why:

* Tall and Cone Shaped: Stratovolcanoes are known for their steep, conical shape.

* Ash and Lava Alternating: These volcanoes erupt explosively, releasing ash and pumice, which build up in layers. Between these eruptions, lava flows can occur, solidifying and creating additional layers. This alternating pattern of ash and lava is characteristic of stratovolcanoes.

Examples of stratovolcanoes:

* Mount Fuji (Japan)

* Mount Vesuvius (Italy)

* Mount Rainier (USA)

* Mount Kilimanjaro (Tanzania)
