Explanation:
Detailed explanation-1: -Basalt plateau refers to an extensive, thick, smooth flow or succession of flows of high-temperature, fluid basalt erupted from fissures, flooding topographic lows, and accumulated to form a plateau. It is the least explosive type of volcano.
Detailed explanation-2: -Basaltic eruptions are the most common form of volcanism on Earth and planetary bodies. The low viscosity of basaltic magmas inhibits fragmentation, which favours effusive and lava-fountaining activity, yet highly explosive, hazardous basaltic eruptions occur.
Detailed explanation-3: -Shield volcanoes, such as those that make up the Islands of Hawai’i, are composed almost entirely of basalt.
