Volcanoes help create new land because after they erupt the lava (called magma when still inside the volcano) begins to solidify at the bottom and turns into land.

ex: Hawaii: the island started out as an under water volcano (caused by sea floor spreading) and after eruptions it began to build up until it peaked out of the ocean. It kept building up until it formed a large land mass.
