What type of magma is typically associated with stratovolcanoes?
What type of magma is typically associated with stratovolcanoes?
- High-silica or rhyolitic magma
- Viscous magma
- Intermediate silica or andesitic magma (correct)

What is the main difference between volcanic domes and monogenetic cones?
What is the main difference between volcanic domes and monogenetic cones?
- Volcanic domes are mound-shaped, while monogenetic cones are cone-shaped
- Volcanic domes are typically found in clusters around a central crater, while monogenetic cones are usually solitary
- Volcanic domes are associated with low silica or basaltic magma, while monogenetic cones are associated with high-silica or rhyolitic magma
- Volcanic domes are formed by repeated slow extrusion of viscous magma, while monogenetic cones are formed by explosive eruptions (correct)
