Repeated eruptions of relatively fluid lava from fissures (Columbia River Plateau, Deccan Traps)can eventually cause an area to be covered by flood basalts.

Question

Quizplus · Accepted Answer

Repeated eruptions of fluid lava from fissures can indeed lead to the formation of flood basalts, as seen in the Columbia River Plateau and Deccan Traps. These eruptions tend to produce large volumes of relatively thin and runny lava, which can spread out over large areas and create vast sheets or layers of igneous rock. Over time, these flood basalts can completely cover the landscape, forming distinctive plateaus or plains.
