The Columbia Plateau in Washington, Oregon, and Idaho is a flood basalt plateau. It formed during the Pliocene period and is one of the largest flood basalts to ever form on the planet.
The Columbia Plateau flood basalts were very fluid eruptions along lengthy fissures. Being very fluid, they didn't pile up, but rather flowed outward in broad sheets. Volcanic peaks are formed around central vents. As the lava pours out it solidifies generally not very far from its source, stacking up layer upon layer.
One or a succession of high-temperature basaltic lava flows from fissure eruptions which accumulate to form a plateau. Also known as flood basalt.answered by sona
what it does is rains so much for hours that it starts to pile up and flood the earth.
We do not no its all to do wth climate change
Yes

Columbia Plateau lies across parts of the United States of Washington, Oregan and Idaho. It is a wide flood basalt plateau and is cut through by the Columbia river.

because of the monsoon flood and the plateau is high
