Is Hawaii built on lava?
This upwelling of molten rock, known as a “hot spot,” creates volcanoes that spew out lava (magma that reaches Earth’s surface). The lava then cools and hardens to create new land. The Hawaiian Islands were literally created from lots of volcanoes—they’re a trail of volcanic eruptions.
