What can you conclude about the kind of lava that formed the volcano?

The type of lava that formed a volcano can be inferred from its shape and eruption style. For instance, shield volcanoes typically produce low-viscosity basaltic lava, resulting in broad, gently sloping sides, while stratovolcanoes are associated with more viscous and explosive lava, often andesitic or rhyolitic, leading to steeper profiles. Additionally, the presence of certain minerals and gas emissions during eruptions can provide further clues about the lava's composition. Overall, the volcano's characteristics and eruptive history reveal insights about the nature of the lava that formed it.
