Lava features are geological formations created by the movement and cooling of molten rock, known as lava, from a volcano. When lava erupts, it can flow across the landscape, forming various shapes such as lava tubes, pahoehoe, and aa. These features provide insight into the type of volcanic activity and the composition of the lava. As lava cools and solidifies, it can create unique structures like lava plateaus and volcanic domes. The texture and appearance of these formations depend on factors such as the lava's temperature, viscosity, and the environment in which it cools. Understanding these features helps scientists study volcanic behavior and the Earth's geological history.
