Answer:

They are all stratovolcanoes.

What are the names of the different types of volcanoes?

Volcanic fissures are linear vents on the surface of a volcano through which lava erupts.

Shield volcanoes are long, flat volcanic islands that form as a result of effusive eruptions and have varying eruption styles.

Dome volcanoes, as their nomenclature implies, look like a dome or a semi-circle and, like shield volcanoes, are formed as a result of effusive eruptions. They are also classified by their plinian eruption style and highly silicic and therefore viscous magma.

Cinder cones are steep, conical hills that are made up of pyroclastic fragments that accumulate around a vent with 30–40° slopes and are monogeneric, meaning that they erupt only once.

Stratovolcanoes are made up of multiple layers of lava flow, hence their famously perfect cone shape as they are continuously rebuilt, and have 50–70° slopes. They also have a plinian eruptive style and parasitic cones.

Lastly, calderas are craters that were former stratovolcanoes with depressions caused by collapsed magma chambers, the result of a final (and most probably large-scale) eruption, and have a diameter of at least two kilometers.
