Stratovolcanoes are a type of volcano characterized by their steep, conical shape and the alternating layers of lava flows, volcanic ash, and other pyroclastic materials. They are one of the most common types of volcanoes and are found on every continent, including the ocean floor. Stratovolcanoes are typically composed of andesitic and dacitic rock, which are high in silica and have a high viscosity, leading to explosive eruptions.

The formation of stratovolcanoes is closely linked to subduction zones, where one tectonic plate is forced beneath another. This process creates a magma chamber beneath the Earth's surface, which feeds the volcano. The magma is rich in silica and gases, which contribute to the explosive nature of stratovolcano eruptions.

Stratovolcanoes are known for their violent eruptions, which can produce pyroclastic flows, lahars, and ashfall. These eruptions can have significant impacts on the surrounding environment and human populations. Some of the most famous stratovolcanoes include Mount Fuji in Japan, Mount St. Helens in the United States, and Mount Vesuvius in Italy.

Despite their potential for destructive eruptions, stratovolcanoes also play a crucial role in the Earth's geological processes. They contribute to the recycling of materials within the Earth's crust and are a significant source of minerals and other resources. Additionally, the fertile soils produced by volcanic activity support diverse ecosystems and agricultural activities.
