Which of the following volcanic landforms is formed by the accumulation of highly viscous acidic lava that solidifies quickly around the vent, forming steep-sided, convex mounds?
A. Shield volcano
B. Flood basalt plateau
C. Volcanic dome or lava dome✓ Correct Answer
D. Cinder cone
💡 Solution & Explanation
Volcanic domes are steep-sided, mound-like structures formed when highly viscous, silica-rich lava extrudes slowly and cools rapidly around the vent without spreading out. Other choices like shield volcanoes are formed by fluid, low-viscosity basaltic lava that travels great distances to create gently sloping profiles. Physical geography questions often contrast these eruptive styles and associated landforms.
