A shield volcano is a broad, gently sloping landform created by the eruption of low-viscosity basalt lava that can flow over long distances. These volcanoes are characterized by their dome-like shape and are primarily formed from repeated, non-explosive eruptions, making them different from steeper stratovolcanoes. The low viscosity of the lava allows it to spread out and create the shield-like profile, which is commonly seen in volcanic regions such as Hawaii.
