The correct response describing the features of most stratovolcanoes is:
steep sides near the top with thick, slow-moving lava
Stratovolcanoes typically have steep profiles and are characterized by explosive eruptions due to the viscous nature of the lava, which can trap gases. This combination leads to more violent eruptions compared to other types of volcanoes, such as shield volcanoes that have gentler slopes and produce thinner, more fluid lava.
