What is Lava?
Lava is molten rock erupted from a volcano. It is a complex mixture of silicate minerals, dissolved gases, and other elements. The appearance of lava varies greatly depending on its composition, temperature, and the rate at which it cools. It can range from smooth, ropy pahoehoe to rough, blocky aa lava. Lava flows can create various landforms, including lava plateaus, lava tubes, and volcanic cones.
