A volcanic plateau is a flat, elevated area formed by the eruption of lava that spreads over a large region. These eruptions typically occur from fissures or cracks in the Earth's crust, allowing molten rock to flow out and solidify. Over time, repeated eruptions can build up thick layers of basalt, creating a broad, level landscape. One well-known example of a volcanic plateau is the Columbia River Plateau in the United States. This region was shaped by extensive lava flows from ancient volcanic activity, resulting in a vast area of flat land that is now home to diverse ecosystems and agricultural activities.
