Hot spot volcanoes that form on the ocean floor are typically associated with mantle plumes, which are columns of hot, solid material rising from deep within the Earth's mantle. As these plumes reach the lithosphere, they melt to create magma, leading to volcanic activity. Over time, this can result in the formation of underwater volcanoes or seamounts. Notable examples include the Hawaiian Islands, which have formed as the Pacific Plate moves over a stationary hot spot.
