Earth Science : Volcanoes

The video explores different types of volcanoes, including shield volcanoes, stratovolcanoes, and cinder cones. It explains how each type forms and their unique characteristics. Shield volcanoes are built by layers of lava and have broad, flat shapes. Stratovolcanoes are tall and symmetric, known for their explosive eruptions and pyroclastic flows. Cinder cones are smaller, formed by lava cinders falling around a vent. The video also highlights notable examples like Mauna Loa, Mount Fuji, and Mount St. Helens.
