Volcanoes are classified into three main types based on their shape and eruption style: shield volcanoes, cinder cone volcanoes, and stratovolcanoes.
- Shield volcanoes have broad, gentle slopes and erupt low-viscosity lava that flows easily over large areas, creating wide, shield-like shapes. An example is Kilauea in Hawaii.
- Cinder cone volcanoes are smaller, steep-sided cones formed by explosive eruptions that throw ash and rocks into the air, which then pile up around the vent. Parícutin in Mexico is a famous cinder cone.
- Stratovolcanoes (or composite volcanoes) are large, steep volcanoes built by alternating layers of lava and ash. They are often highly explosive, like Mount St. Helens in the U.S.
Each type of volcano behaves differently, with varying levels of explosiveness and eruption patterns.
Stratovolcanoes are typically the most explosive type of volcano. (TRUE or FALSE)
