A lava flow is a mass of molten rock that moves across the Earth’s surface during a volcanic eruption. Lava flows can vary in composition, viscosity, and temperature, influencing their behavior and impact on the landscape. Studying lava flows is important for understanding volcanic processes, hazards, and the formation of volcanic landforms.
