The Volcanic Origins And Basalt Composition Of The Hawaiian Islands
Formed by volcanic eruptions and plate tectonics, the Hawaiian Islands consist primarily of basalt, an igneous rock known for its dark color and fine-grained texture. Basalt’s low viscosity allows it to flow easily, creating shield volcanoes with gently sloping sides. Magma generated beneath the Earth’s surface ascends and erupts, forming these volcanic structures that define…
