Lava plateaus are flat, elevated areas formed by the repeated eruption of lava that spreads over large distances. These eruptions typically occur from fissures in the Earth's crust, allowing molten rock to flow out and solidify, creating a broad, level surface. Over time, layers of lava build up, resulting in a plateau that can be several hundred meters high. One of the most famous examples of a lava plateau is the Columbia River Basalt Group in the United States. This region features extensive basalt formations created by volcanic activity millions of years ago. Lava plateaus can also influence local ecosystems and landscapes, providing unique habitats for various plant and animal species.
