When a common type of basaltic lava hardens, it forms AA lava, which is characterized by its rough, jagged surface. This texture results from the high viscosity of the lava, causing it to break into angular blocks as it cools. AA lava typically flows more slowly than the smoother, more fluid pahoehoe lava, making it more challenging to traverse. Its appearance is often associated with cooler temperatures and higher gas content during eruption.
Basalt forms when basaltic lava cools and solidifies at or near the Earth's surface. When basaltic magma cools and solidifies below the surface, it can form a type of igneous rock known as gabbro. Both basalt and gabbro are composed primarily of plagioclase feldspar and pyroxene, but they differ in their formation and texture due to their cooling environments.

Basalt is the igneous rock that forms when basaltic lava cools and hardens. It is fine-grained and dark in color, typically containing minerals such as pyroxene and plagioclase.

Kilauea produces basaltic lava, which is the most common type.

Lava plateaus form when fluid basaltic lava flows out of fissures.
