At many convergent plate boundaries, dense lithosphere melts or slides beneath less-dense lithosphere in a process called subduction, creating a trench. "Five of the Solomon Islands disappeared" due to sea level rise, how is this possible so quickly? By arbitrary definition, seamounts must be at least 3000 ft (about 900 m) high, but in fact there is a continuum of smaller undersea mounts, down to heights of only about 300 ft (100 m). Over time, countless eruptions cause the seamount to grow until it finally emerges above sea level to form an island volcano. They can be isolated or part of large mountain chains.
