WebMay 12, 2024 · The 3 types of volcanoes are: Stratovolcanoes. Shield volcanoes. Cinder cones. Let’s dive into the differences between these types of volcanoes: 1. Stratovolcanoes (Composite Cones) Stratovolcanoes are tall and cone-shaped. Instead of flat shield volcanoes like in Hawaii, they have bigger peaks. Shield volcanoes are distinguished from the three other major volcanic types—stratovolcanoes, lava domes, and cinder cones—by their structural form, a consequence of their particular magmatic composition. Of these four forms, shield volcanoes erupt the least viscous lavas. Whereas stratovolcanoes and lava domes are the product of highly viscous flows, and cinder cones are cons…

Web40. Pyroclastic flows are fast-moving currents of hot gas and volcanic materials that are associated with explosive eruptions, which are more likely to occur at volcanoes with silicate magma composition. 41. Shield volcanoes have gentle slopes and are composed of multiple layers of mafic lava flows, which give them their characteristic flat shape.

WebMay 26, 2010 · Shield volcanoes are broad, gently sloping volcanic cones that are usually tens or hundreds of square kilometers in extent. They form where large volumes of gas-poor basaltic magma erupted from vents along fissures. As successive eruptions build layers onto the volcano, it gains both area and elevation.
