1. Shield Volcanoes: These are large, gently sloping volcanoes built up by fluid lava flows. They are typically associated with effusive eruptions, where lava flows smoothly and slowly. Examples include Mauna Loa in Hawaii and Kilauea.
2. Stratovolcanoes (Composite Volcanoes): These are cone-shaped volcanoes with steep slopes, formed by alternating layers of lava flows and ash. They are known for their explosive eruptions, which can be very destructive. Examples include Mount Fuji in Japan and Mount Vesuvius in Italy.
3. Cinder Cones: These are relatively small, steep-sided volcanoes formed by the accumulation of tephra (rock fragments and volcanic ash). They are usually associated with short-lived, explosive eruptions. Examples include Parícutin in Mexico and Sunset Crater in Arizona.
