How does the volcano on the bottom of the ocean floor reach to be above air?

Underwater volcanoes, known as submarine volcanoes, can erupt and build up layers of lava over time. When these eruptions occur, the lava cools and solidifies, eventually forming a volcanic island if enough material accumulates above sea level. The process involves tectonic activity, where magma rises through cracks in the Earth's crust, and repeated eruptions contribute to the growth of the volcano. Eventually, if the volcanic activity continues, the structure can rise high enough to breach the ocean's surface.
