There are three main types of volcanoes based on their shape and eruption characteristics:
-
Stratovolcanoes (composite volcanoes): These are tall and steep-sided volcanoes with explosive eruptions caused by the buildup of gas pressure within the magma chamber.
-
Shield volcanoes: These are broad, gently sloping volcanoes characterized by low-viscosity lava flows that can travel long distances. They are typically not as explosive as stratovolcanoes.
-
Cinder cone volcanoes: These are small, steep-sided volcanoes formed from layers of volcanic debris (cinders, ash, and rocks) ejected during explosive eruptions. They usually have short-lived eruptions.
These are the main types of volcanoes based on their physical characteristics and eruption styles.
