The feature of most shield volcanoes is a broad base. To get the answer to this question, you can either recall your knowledge about shield volcanoes or conduct a quick search on reliable sources such as scientific websites or textbooks. Shield volcanoes are characterized by their broad, gently sloping sides, resembling a shield or a warrior's shield lying on the ground. The lava flows from shield volcanoes tend to be relatively thin and runny, which allows them to cover a wide area before cooling and solidifying. Unlike other types of volcanoes, such as stratovolcanoes, shield volcanoes generally have non-explosive eruptions, with lava flowing out relatively calmly rather than violently erupting.
