I apologize for any confusion. Here is the most accurate answer:
Shield volcanoes typically have gently sloping sides, resembling a broad shield or flattened dome shape. They are generally not as steep as other types of volcanoes, such as stratovolcanoes. Additionally, shield volcanoes are typically formed by multiple eruptions from a central vent or multiple vents, rather than a single vent. They are also known to have a relatively low explosive activity and are not usually considered as destructive as some other types of volcanoes.
