19 de oct. de 2023 · Learn about volcanoes, their types, eruptions, and features. Find out how volcanoes are classified as active, dormant, or extinct and how they form on land and underwater.
Learn the difference between stratovolcanoes and shield volcanoes, and how lava domes and calderas form from erupted magma. See examples of different types of volcanoes around the world, such as Mauna Kea, Mauna Loa, Andesite and Soufrière Hills.
Learn about the different types of volcanoes, how they are classified by size, form, eruption history and style, and how they vary in rock type and features. See examples of cinder cones, composite volcanoes, shield volcanoes, and other types of volcanoes in national parks and other units of the National Park System.
Each type of volcano has characteristic features that distinguish it from other types. Volcanoes differ in appearance because of the composition of their magma and the processes that originally created them.
There are many different types of volcanic eruptions and associated activity: phreatic eruptions (steam-generated eruptions), explosive eruption of high-silica lava (e.g., rhyolite), effusive eruption of low-silica lava (e.g., basalt), sector collapses, pyroclastic flows, lahars (debris flow) and carbon dioxide emission.
