A steamship is a large boat that is powered by steam. Steam is a gas that is formed when water gets very hot. Steam has the power to make things move. Steamships were built to be strong, and they had enough power to cross oceans. Steamships are not used much anymore because modern ships use a different type of power. Steamships were used mainly in the nineteenth century.
Before steamships were invented, sea travel was done using ships that had sails and used only wind power.- similar words:
