Types of Volcanic Landforms

Volcanic landforms are broadly classified by their shape, eruption style, and thee visosity of thee lava that builds them. The primary type included shield wulcan, stratowulcan, cinder cones, lava domes, and calderas. Each type reflects a distint combination of magma chemory, gas content, and tectonic setting.
